Answer:
1/49
Step-by-step explanation:
7^-2
1/49
7^2 is usually 49 for negative exponents just flip it
A. (4)5 x (4)4 = 36 OR 4(5 x 4) = 36
b. No you would not. 5(5 x 4) = 45 which is out of your budget.
To solve this problem you must apply the proccedure shown below:
1. The area of the rectangle is:

Where
is the width and
is the length.
2. Based on the data given, solve for the width and then substitute the values of the length and the values of the area. Therefore, you have:

The answer is the second option:

I’m pretty sure you can just do 1/2! since B is 0.75 and A is 0.25 so 0.75-0.25=0.5=1/2
