Answer:
9x² -6x -8
Step-by-step explanation:
The area is the product of length and width.
A = LW
A = (3x +2)(3x -4) = 3x(3x -4) +2(3x -4)
A = 9x² -12x +6x -8
A = 9x² -6x -8 . . . area of the rectangle

Answer:
1. (256/3)π ft³
2. 33.49 ft³
Step-by-step explanation:
1. Put 4 ft into the formula where r is, then simplify.
V = (4/3)π(4 ft)³ = (256/3)π ft³
__
2. The radius is half the diameter, so is 2 ft. Put that in the formula, along with the value for π, and do the arithmetic.
V = (4/3)(3.14)(2 ft)³ ≈ 33.49 ft³
On a hiking trail map, the distance from mountain peak A to mountain peak B is 12.3 inches. The actual distance is about 1,000 miles. What is the distance on the same map from river A to river B if the actual distance is about 100 miles?
Answer:
The distance of the rivers on the map is of 1.23 inches.
Step-by-step explanation:
We use proportions to solve this question, by a rule of three.
We have that:
If the actual distance is of 1000 miles, the distance on the map is of 12.3 inches. If the actual distance is 100 miles, what will be the distance on the map?
1000 miles - 12.3 inches
100 miles - x
Applying cross multiplication
[tex]1000x = 12.3*100[/tex]
[tex]1000x = 1230[/tex]
[tex]x = \frac{1230}{1000}[/tex]
[tex]x = 1.23[/tex]
The distance of the rivers on the map is of 1.23 inches.

What is the area of a square with side lengths of 3/5 units?
To find the area of a square, multiply the side length by itself, also known as sqaring the side length.We must solve 3/5 x 3/5.3/5 x 3/5 = 0.36The units we'll use is because units are the unt we're given, and it is squared because it is the area of a shape.

Andre and Jillian were shopping at the same grocery store for bottles of sports drinks for their kickball teams. Andre bought 3
packs of bottled drinks, plus 11 single bottles. Jillian purchased 5 packs, plus 3 singles. Andre and Jillian discovered that they
had purchased the same number of bottles. How many bottles were in each of the packs? (All of the packs have the same
number of bottles.)
Answer:
x = 4
Step-by-step explanation:
The equation comes out to be:
3x + 11 = 5x + 3
Move the variables to the left-hand side and change its sign
And move the constant to the right-hand side and change its sign:
3x - 5x = 3 - 11
Combine like terms to get:
-2x = -8
Isolate x by dividing -2 on both sides:
-2x/-2 = -8/-2
x = 4
The number of bottles in the pack is 4.
Expressions that represent the total bottles boughtThe expression that can be used to represent the number of bottles bought by Andre is 3p + 11.
The expression that can be used to represent the number of bottles bought by Jillian is 5p + 3
Where:
p = number of bottles in the packs bought
Determining the number of bottles in the packIf both Andre and Jillian have the same number of bottles, their expressions would be equal
3p + 11 = 5p + 3
In order to determine the value of p, take the following steps:
Combine similar terms
5p - 3p = 11 - 3
2p = 8
Divide both sides of the equation by 2
p = 4

Step-by-step explanation:
We have been investigating whether alloantigen-specific CD4(+)25+ regulatory T cells can be identified for use in treating graft-versus-host disease. CD150, which is upregulated on the surface of all activated T lymphocytes, was identified as a candidate marker for alloantigen-activated CD4(+)25+ regulatory T cells by gene chip analysis. Freshly isolated CD4(+)25+ cells had only low cell-surface expression of CD150, comparable to that of CD4(+)25- T cells. Increased CD150 expression was observed on all T cells after coculture with allogeneic stimulator cells. When purified CD4(+)25+ cells were precultured with allogeneic stimulator cells, then sorted into CD150+ and CD150- subsets, allosuppressive activity was contained primarily in the CD150+ fraction. These cells also suppressed the proliferation of alloantigen-activated autologous T cells, and they could be expanded in vitro without loss of their suppressive capacity. These results suggest that CD150 can be used as a marker for the identification of purified alloantigen-activated CD4(+)25+ regulatory T cells.
A man goes into a store and says, “If you give me as much money as I have with me now, I will spend $10 in your store.” The store owner agrees, and the man spends the money.
He goes into a second store and again says, “If you give me as much money as I have with me now, I will spend $10 in your store.” Again, the owner agrees, and the man spends the money.
In a third store, he repeats his proposition. The proprietor agrees, and the man spends the money.
At this point, the man has no money left. How much money did he have to begin with?
Answer:
$8.75
Step-by-step explanation:
Let x = the amount the man originally had
The man has $x and says "if you give me $x, I will spend $10."
y = amount he has after 1st proposition = x + x - 10 = 2x - 10
He repeats this procedure, now with $2x-10 in his pocket...
z = amount he has after 2nd proposition = (2x - 10) + (2x - 10) - 10 = 4x - 30
He repeats this procedure, now with $4x-30 in his pocket...but this time he is left with zero dollars...
r = amount he has after 3rd proposition = (4x-30) + (4x-30) - 10 = 8x-70 = 0
8x - 70 = 0,
x = $8.75

Elisa is making strawberry shortcake. One serving of strawberry shortcake requires one third cup of strawberries and one shortbread biscuit to feed one person. Elisa has a dozen shortbread biscuits and three cups of strawberries. How many people can Elisa serve strawberry shortcake to? How many cups of strawberries will Elisa need if she wants to use all dozen shortbread biscuits? Show all your mathematical thinking.
PLEASE HELP!
Given, To make a strawberry shortcake for one person, we need :
▪︎[tex] \frac{1}{3} [/tex] cup of strawberry
▪︎one shortbread biscuit
Quantity of strawberries Elisa has = 3 cups
Number of shortbread biscuits she has = 12
Number of shortcakes she can make :
[tex] = \tt3 \div \frac{1}{3} [/tex]
[tex] = \tt\frac{3 \times 3}{1} [/tex]
[tex]\color{plum} =\tt 9 \: people[/tex]
Thus, Elisa can serve strawberry shortcakes to 9 people.
With 12 dozen shortbread biscuits she can serve 12 people.
Quantity of strawberries needed to serve 12 people :
[tex] =\tt \frac{1}{3} \times 12[/tex]
[tex] =\tt \frac{12}{3} [/tex]
[tex]\color{plum} = \tt4 \: cups[/tex]
○=> Therefore :▪︎Elisa can serve strawberry shortcakes to 9 people.
▪︎Elisa will need 4 cups of strawberries if she wants to use all dozen shortbread biscuits.

Right format of question:
Plot two points that are 7 units from Point D and also share the same x-coordinate as Point D.
Answer:
[tex]D' = (-4,-6)[/tex] and [tex]D' = (-4,8)[/tex]
Step-by-step explanation:
Given
[tex]D(x,y) = (-4,1)[/tex]
Required
Determine a point 7 points from D and in the same x coordinate
Represent this point with D'.
From the requirement of the question, D' has two possible values and these values are:
[tex]D' = D(x,y-7)[/tex] ----> 7 units down and
[tex]D' = D(x,y+7)[/tex] ----> 7 units up
Substitute values for x and y in [tex]D' = D(x,y-7)[/tex] and [tex]D' = D(x,y+7)[/tex]
So, we have:
[tex]D' = D(x,y-7)[/tex]
[tex]D' = (-4,1 - 7)[/tex]
[tex]D' = (-4,-6)[/tex]
[tex]D' = D(x,y+7)[/tex]
[tex]D' = (-4,1+7)[/tex]
[tex]D' = (-4,8)[/tex]
