Answer:
b Superscript positive
Step-by-step explanation:
Negative exponents in the denominators can be evaluated by moving the function from the denominator to the numerator and changing the power from negative to the positive.
We have
1/b⁻² = b²
Moving the function with a power from denominator to numerator or from numerator to denominator changes the sign of the power. It is not equal to zero.
This is the property of exponents.
It represents simulations
Answer:
the width is ≤ 38 feet
Step-by-step explanation:
the perimeter of a rectangle is given by the relation : 2*( length + width)
P ≤ 120
2 (L + W) ≤ 120
L + W ≤ 60 ,,, L = 22
22 + W ≤ 60
W ≤ 38 feet
