Answer:
6mi per 1.5h
Step-by-step explanation:
4miles per 1h
6miles per 1.5h
4×1.5=6
-5t^2 +2t -3
Collect terms in the sum:
G+P = (3t^2 -5t +6) +(-8t^2 +7t -9) = (3-8)t^2 +(-5+7)t +(6-9)
= -5t^2 +2t -3
The slope to the question provided is
Similar triangles
x / 12 = (4+12) / x
Cross multiply
x^2 = 12 * 16
x^2 = 3 * 64
x = 8√3
Answer is B. 8√3
