For 8, 15.25*18=274.5, 274.5/2= 137.25 or 137 1/4
for 9, 11*13=143, 143/2= 71.5 or 71 1/2
The equivalent rate to 9 miles in 45 minutes is C. 13.5 miles in 67.5 minutes
<h3>How to calculate the value?</h3>

Answer:
Perimeter = 6x² + 8x
Step-by-step explanation:
Perimeter = 2(length + width)
perimeter = 2((x²+x)+(2x²+3x))
perimeter = 2(x²+2x² + x+3x)
perimeter = 2(3x² + 4x)
perimeter = 2*3x² + 2*4x
perimeter = 6x² + 8x
1. Number that adds up to -12 and multiplied by the same # that gives u -13. Set it up like this because both are negative so, u need 1 negative and 1 positive.
(x-13)(x+1)
2. Same rule applies. GCF
8y(4y+1)
3. (x+3)(x-3)
