(a+2b)² ?????????????????????
Answer:
a² + 4ab + 4b²
Step-by-step explanation:
Given
(a + 2b)²
= (a + 2b)(a + 2b)
Each term in the second factor is multiplied by each term in the first factor, that is
a(a + 2b) + 2b(a + 2b) ← distribute both parenthesis
= a² + 2ab + 2ab + 4b² ← collect like terms
= a² + 4ab + 4b²
Find the real numbers x and y that make the equation true. (2 points)
-3 + yi = x + 6i
Answer:
x = - 3, y = 6
Step-by-step explanation:
For the 2 sides to be equal then the coefficients of the imaginary terms and the real terms must be equal.
Given
- 3 + yi = x + 6i , then
x = - 3 and y = 6

What postulate or theorem can be used to prove that these two triangles are congruent?
PLEASE HELP I REALLY NEED IT!!!
I will give brainliest.
Use the picture
Step-by-step explanation:
The attached figure shows two triangles AOB and MON.
In triangles AOB and MON,
AB = MN (Given )
∠AOB = ∠MON (vertically opposite angles)
∠O = ∠O (common)
∴ ΔAOB ≅ Δ MON (ASA)
Angle-side-angle is the postulate that can be used to prove that two triangles are congruent.
The population of town A increases from 1,346 to 1,500. In the same period, the population of town B increases from 1,546 to 1,800.
a. Find the percent of increase in population for town A and for town B.
b. Which town had the greater percent of increase?
a. you would do 1346/1500 to get 0.8973333333333. i you want to check that you can do 1346/0.8973333333333 and you would get 1500. I'm just going to round 0.8973333333333 down to 0.897. So for town B you would also do 1546/1800 which brings you to 0.858889 you can again do 1546/0.858889 but i found that 0.8588888888 gives you the most accurate answer. so rounding that down to 0.859
b. you can see that 0.897 is a larger percent that 0.859 so town a had a larger increase than b
The answer is 33 but I don’t how to show the work so can someone help me pls :/
Answer:
Gather your like terms together
Step-by-step explanation:
(x+4x+x) = 6x
(-10-10+2) = -18
6x -18 = 180 (the sum of triangle angles)
Add 18 to both sides
6x = 198
divide 198 by 6
x = 33

The sum of 3 and a number is between -2 and 17.
Answer:
The number, x = { -5 < x < 14}
This means x is any integer between -5 and 14
Step-by-step explanation:
From the statement, let the number be x
3 + x = y; y = { -2 < y < 17}
This means that y is any integer between -2 and 17
Therefore, x = y - 3
Subtract 3 from the limits of y
i.e. -2 - 3 = -5 and 17 - 3 = 14
Hence, x = { -5 < x < 14}

Lola's hockey team lost 15% of
their games this season. If they
lost 3 games, how many games
did they play in total?
(show your work)
Answer:
[tex]20[/tex]
Step-by-step explanation:
Let [tex]x[/tex] = games played in total
From the fact that [tex]15\%[/tex] of the games the team played is equivalent to [tex]3[/tex] games, we can write:
[tex]15\%x = 3[/tex]
[tex]x=3\div 15\%[/tex]
[tex]=20[/tex]
∴ Lola's hockey team played a total of 20 games.
Hope this helps :)

9514 1404 393
Answer:
25
Step-by-step explanation:
As always, you identify the possible relationships between the given values. Make use of those to find the unknown. Then use that value as required to answer the question(s) posed.
The triangle is isosceles, so AB = AC.
AB = AC
4x +1 = 2x +23
2x = 22 . . . . . . . . . subtract (2x+1)
x = 11
With this value of x, we can find BC.
BC = 3x -8
BC = 3×11 -8
BC = 25 . . . . units

Help me classify the triangles by its sides and measuring its angles :)
actually answer this
Answer:
1. isosceles
2. Right
Step-by-step explanation:
Here, we want to give the kind of triangle in each of the diagrams
1. From what we can see, we have two sides equal to each other using the given markings. More specifically, the base sides are equal and that makes the triangle an isosceles triangle
2. From what we can see here, we have an angle of 90 degrees on one of the sides of the triangle. In other words, we have a right angle on one of the sides.
This makes the triangle, a right triangle

A box of granola weighs 24 ounces and a box of bran flacks weighs 6/8 as much as the ronal A box of Corn Pops weighs 1 1/8 as much as the ronal what is the least number of ounces found in either box or ronal bran flakes or Corn Pops
Answer:
54 ounces
Step-by-step explanation:
A box of granola weighs 24 ounces and a box of bran flacks weighs 6/8 as much as the ronal
The number of ounces of the bran flakes = 6/8 of the box of the granola
= 6/8 × 24 ounces
= 18 ounces
A box of Corn Pops weighs 1 1/8 as much as the granola
Hence, the number of ounces of the box of corn pops =
1 1/8 of the granola box
= 9/8 × 24 ounces
= 27 ounces
The least number of ounces found in either box or ronal bran flakes or Corn Pops is calculated as:
We solve using LCM Method
Multiples of 18:
18, 36, 54, 72, 90
Multiples of 27:
27, 54, 81, 108
Therefore,
LCM(18, 27) = 54
The least number of ounces found in either box or ronal bran flakes or Corn Pops is 54 ounces

The area of a metal frame being built by a construction company can be represented by the function A(w)=4w2+34w , where represents the width in meters of the frame. What is the area of the frame in square meters when the width equals 1 meter?
Answer:
38 square meters
Step-by-step explanation:
Given:
A(w)=4w²+34w
The function represent the area of a metal frame being built by a construction company
What is the area of the frame in square meters when the width equals 1 meter?
Find A(w) when w = 1 meter
A(w)=4w²+34w
A(1) = 4(1)² + 34(1)
= 4 + 34
= 38 square meters
A(1) = 38 square meters
