Answer:
92.5 cm²
Step-by-step explanation:
Lets take this step by step
Bottom rectangle is 2 by 5, so then 2*5 = 10
Large rectangle is 8 by 9, so 8*9 = 72
The triangle is 7 by 3, you get the 7 by subtracting the 5 side from the square because using the square you can tell that the height is 9 - something.
The 5 you get is from subtracting the cut part that you might have made because the height of that is 2, therefore you cut off 2 from 7 making it 5
Triangle area is h*b / 2, therefore 7*3 = 21/2 = 10.5
Add them all together, 10.5 + 10 + 72 and you get 92.5
Answer:Divide both sides by the numeric factor on the left side, then solve.

Answer:
A
Step-by-step explanation:
I believe it is A because there is not any repeating X's. There is a repeating y which is 1. Therefore it is A.
Translating that problem into an equation with x as a variable we get 3x + x +10 = 22. Combine like terms to get 4x + 10 = 22. Subtract 10 on both sides to get 4x = 12. Divide by 4 on both sides to get x = 3.
Now to plug in. The first number was represented by 3x. So substituting 3 for the x we get 3(3) = 9. And again for the second number represented by x+10, 3+10 = 13.
Your numbers are 9 and 13. To check just add them together. 13 + 9 is 22, I'll save ya the effort.
210/= 30 so the answer is 30
