Answer:
16b^4-9
Step-by-step explanation:
Factoring gives us 16b^4+12b^2-12^2-9. Simplifying gives us the answer which is 16b^4-9
Answer:
[tex]16b^4-9[/tex]
Step-by-step explanation:
When multiplying binomials, we can use a method called FOIL (First-Outside-Inside-Last).
For [tex](t_1+t_2)(t_3+t_4)[/tex], let:
[tex]t_1\implies \text{First Term},\\t_2\implies \text{Second Term},\\t_3\implies \text{Third Term},\\t_4\implies \text{Fourth Term}[/tex]
In the FOIL method, the steps go:
[tex]\text{\textbf{F}irst: Multiply the first and third terms (first term of each binomial)},\\\text{\textbf{O}utside: Multiply the first and fourth terms},\\\text{\textbf{I}nside: Multiply the second and third terms},\\\text{\textbf{L}ast: Multiply the second and fourth terms (last term of each binomial) }[/tex]
Given [tex](4b^2+3)(4b^2-3)[/tex], we have:
[tex]\text{First: }4b^2\cdot 4b^2,\\\text{Outside: }4b^2\cdot -3,\\\text{Inside: }3\cdot 4b^2,\\\text{Last: }3\cdot -3,\\\rightarrow 16b^4-12b^2+12b^2-9[/tex]
Combine like terms:
[tex]\boxed{16b^4-9}[/tex]
The wheels ona bike have a diameter of 26 inches. How many full revolutions will the wheels need to make to travel 100 feet?
Answer:
82 revolutions Step-by-step explanation:
One revolution will be the circumference of the tire, so multiply pi (3.1416) times the diameter (26 in.) to get 81.68 in. then round it up to 82.
You are using a hose to fill up your backyard swimming pool on a hot day. Water flows out of the hose at a rate of 6 gallons per minute. In the equation below, m is the number of minutes the hose has been running, and g is the number of gallons of water in the pool.
The relationship between these two variables can be expressed by the following equation:
g=6m,
Identify the dependent and independent variables.
Answer:
The independent variable is the m, which is the number of minutes the hose has been running. The dependent variable is the g, which is the gallons per minute.
Answer:
g=36
Step-by-step explanation:
so if g=6m you would do 6x6 as 6 gallons per minute and g is the amount in the pool so you times them to get 35 so g=36

Leon is buying a bicycle. The regular price of the bicycle is x dollars. The bicycle is on sale for 20% off. He has to pay 5% sales tax on the sale price of the bicycle.
To represent his total cost, Leon writes the expression shown. 1.05(x – 0.2x). Which expression also represents Leon’s total cost?
Answer:
B. 0.84
Step-by-step explanation:
Hope this helps
total cost= 1.05(x-0.2x)
= 1.05 (0.8x) = 0.84x
Answer:
B
Step-by-step explanation:
1.05(x - 0.2x) = 1.05x - .21x
1.05x - .21x = .84x

Look at the two patterns below: Pattern A: Starts from 9 and follows the rule "add 8" Pattern B: Starts from 9 and follows the rule "add 2" Select the statement that is true. The terms in Pattern A are 4 times the corresponding terms in Pattern B The terms in Pattern B are one fourth the corresponding terms in Pattern A. The first five terms in Pattern A are 0, 9, 17, 26, 35. The first five terms in Pattern B are 9, 11, 13, 15, 17.
Answer:
It should be the last statement.

Need help with third question!!!!!!!!!!
Answer:
1.
Angle 2 = Angle 4 (alternate angles)Angle 1 = Angle 5 (corresponding angles)2.
Angle 1 + Angle 2 + Angle 3 = 180 (angles on a line)
Now,
Angle 2 = Angle 4 (alternate angles)
and Angle 1 = Angle 5 (corresponding angles)
So,
Angle 1 + Angle 2 + Angle 3 = Angle 5 + Angle 4 + Angle 3 = 180
Hence proved

Answer:
74 ft
Step-by-step explanation:
because the formula for area of a triangle is 1/2 times the length times the height which on this one comes to be about 126 and 20 times 10 is 200, take 126 away from 200 and you get 74.
Answer:
137 square feet of tile
Step-by-step explanation:
First, I will solve for the shaded area:
A=l*w
A=20*10
A=200
Next, I will solve for the triangle
The formula for a right triangle is A=1/2*b*h, and this isosceles is divided into 2 right triangles, so I can use this and multiply by two:
A=1/2*b*h*2
A=b*h (the 1/2 and two cancel each other out)
A=9*7
A=63
Then, we subtract the area of the triangle from the area of the whole rectangle to get the area of the shaded area:
200-63=137
So, the area of the shaded area is 137 square feet of tile.
