Answer:
False.
Step-by-step explanation:
The number 5 IS a coefficient because it is the first number in the expression.
Answer:
C is the answer, as wind turbines are more expensive

Answer:
4w + 10 = 116
Step-by-step explanation:
Call the width w.
The length is 5 more than that, so the length is w + 5
Perimeter is 2w + 2l
2w + 2(w+5) = 116
Distribute the 2 to the values in the parentheses.
2w + 2w + 10 = 116
Combine like terms
4w + 10 = 116
414 is 92% of 450
Therfore, when you subtract 100 - 92
It equals 8
8% is the answer.
