We know the number of yards run per quarter:
Sum of yards run across quarters = (-2) + 14 + (-18) + (-6) = -12
Total number of quarters = 4
⇒
⇒ = -3
Hence, he ran -3 yards per quarter
Answer:
A
Step-by-step explanation:
.......
a). cosA = 4/5
b).
time = 49 hours
speed = 7 miles/hour
speed = distance / time
∴ distance = speed × time
= 7 × 49
= 343 miles
f(x)g(x) = 9x² + 10x - 16
<u>Step-by-step explanation:</u>
Step 1:
Given f(x) = 3x - 4 × 2 + 6x and g(x) = 5x + 2 × 2 - 3x
f(x) = 9x - 8
g(x) = 2x + 4
f(x)g(x) = (9x - 8)(2x + 4)
= 18x² + 36x - 16x -32
= 18x² + 20x - 32
= 9x² + 10x - 16
