Answer:

c =36

Step-by-step explanation:

a perfect square (ax+b)² expanded will become ax² + 2ab + b²

since a is one (x² = 1*x²), 2b = 12, and b = 6

c = b²

c = 6²

c =36

SOMEONE HELP! PLEASE! read the attached files
Trava [24]

Answer: 43 squared units

Explanation:

So the area is the total amount of the inside of the polygon (I’m not good at explaining) and you get your area from using measurements on the sides of the shape for example for a square let’s say the side is 4 and another side is 4 so you multiply that and you get 16 which is the area

So basically since this one is a open polygon you can just count the inside of the poly using the squares

Explain how 9*4 can help you find 9*8
statuscvo [17]
It can help because 9×4 =36, and 9×8=72. if you divide 72 by 2 you get 36 which is the answer to 9 ×4. basically because nine is the same in both problems you are multiplying by 4 (and you know 4 is half of 8) you can assume that multiplying the sum of 4 and 9 that you will get the sum of 8 and 9.

Solve for x. 3(x + 2) + 4(x - 5) = 10 x = 36/7 x = 24/7 x = 16/7 x = 9/7
IRISSAK [1]

3(x + 2) + 4(x - 5) = 10

Use the distributive property:

3x + 6 + 4x - 20 = 10

Combine like terms:

7x -14 = 10

Add 14 to both sides:

7x = 24

Divide both sides by 7:

x = 24/7
