Answer:
121
Step-by-step explanation:
You are missing a parentheses
Assuming you just mean to close the parentheses
((5-(-4)^2)^2)
The first step is to complete the inside parentheses
PEMDAS
(5-(-4)^2)
Do the exponents first
(5-(16))
-11
Put this in the equation for (5-(-4)^2)
(-11) ^2
121
If you divide the area of the rectangle by the length (44÷5.5) the answer is 8. Your answer is 8 ft.
Answer:
See step by step answer
Step-by-step explanation:
the factors are (x+22)(x-10)=0
so x = -22 and 10, but a dimension cannot be negative, so the answer for x is 10 and then if you plug it back in the dimensions are 4 cm, 11 cm and 21 cm.
When you multiply 4 * 11 * 21 = 924, so you know it's correct.
