Let's see what to do buddy...
_________________________________
To do this, we have to multiply the face and denominator of the fraction by the denominator conjunction, which is :

Answer: -69q+74
Step by step:
1. Use distributive property.
8⋅10+8(−6q) + 3(−7q − 2)
Multiply 8 • 10 then -6 • 8
80 - 48q + 3(-7q - 2)
2. Use distributive property again.
80 - 48q + 3(-7q - 2)
Multiply -7 • 3 then 3 • -2
80 - 48q -21q - 6
3. Simplify
Subtract 6 from 80 then subtract 21q from -48q.
-69q + 74
8(10 - 6q) + 3(-7q - 2) = -69q + 74

I hope this answers your question. :)
Time is 16.75 seconds when the arrow reaches 200 ft
Step-by-step explanation:
- Step 1: Find time at height of 200 ft
Height = 200 ft
v = 280 ft/s
Projectile formula, h = -16t² + vt
⇒ 200 = -16t² + 280t
⇒ 16t² - 280t + 200 = 0
⇒ 2t² - 35t + 25 = 0 (dividing by common factor 8)
Using quadratic formula to find t
t = (35 ±√35² - 4×2×25)/2×2
t = (35 ±√1225 - 200)4 = 35 ± 32.02/4
∴ t = 67/4 or 3/4
t = 16.75 seconds
