Answer:
x = 2.5 inches. Or
x = 5/2
Step-by-step explanation:
Length: 7 + 2x
Width: 5 + 2x
Note that you have to add x at each end of the picture and onto each part of the width.
The entire area is 120 square inches.
Formula
L*W = Area
(2x + 7)(2x + 5) = 120
Solution
4x^2 + 10x + 14x + 35 = 120 Subtract 120 from both sides. Add xs
4x^2 + 24x + 35 - 120 = 0
4x^2 + 24x - 85 = 0 Factor
(2x + 17)(2x - 5)
2x + 17 has no meaning. It will give - 8.5 which is not possible.
2x - 5 =0
2x = 5 Divide by 2
x = 5/2
x = 2.5
Note: I don't know which one the computer is looking for.
Answer:
1. - completed
2. expanded = a · a · a · a
3. base = a | exponent = 5 | expanded = a · a · a · a · a
4. - completed
5. base = c | exponent = 3 | expanded = c · c · c
6. base = c | exponent = 4 | expanded = c · c · c · c
7. base = m | exponent = 2 | expanded = m · m
8. base = m | exponent = 3 | expanded = m · m · m
9. power = y⁵ | base = y | exponent = 5
10. power = y⁸ | expanded = y · y · y · y · y · y · y · y

It would go along with, "if I get better grades, then I study."
2nd one: 2 rectangles can have thr same area but have different perimeters.
The answer is 35000. Because 2 significant figures means the 2nd number, in this case it is the number 4 and if we want to round off something, look at the next number, if more than 5 or 5, you must round up.
