Answer:
22% reduction
Step-by-step explanation:
Find the percent decrease by dividing the difference in amounts by the original amount.
Find the difference:
115 - 90 = 25
Divide this by the original amount:
25/115
= 0.217
So, the percent decrease is 21.7%. Round this to the nearest whole percentage:
= 22
The percent reduction in fuel used was approx. 22%

Answer: Equivalent expressions
14⋅x or 6+8x
<span>so to factor the trinomal:
z^2+18z+81
In this problem 9*9=81 and 9+9=18, so insert 9 as the right hand term of one factor and 9 as the right-hand term of the other factor.
(z+9)(z+9)
Combine the two common factors of (z+9) by adding the exponents.
(z+9)^2</span>
