Answer:

-43

Step-by-step explanation:

So first things first you will multiply -9 by 4 and that gives you -36, Next you will add -7 to -36 which gives you -43.

Westkost [7]

Answer: The best estimate for the amount of money she saves to buy clothes = $ 562.5

We can find the side length of square 3 by dividing by 4, which is 9.

Then, we find the side length of square 2 by dividing it by 4, which is 12.

To find the AREA of square 1, we do a^2+b^2=c^2. This is basically adding up area of square 1 and square 2 to get square 3.

a^2+b^2=c^2
9^2+12^2=c^2
81+144=225

So the area is 225 units.
