x^4-8x^2+19
Answer:
p = -3
Step-by-step explanation:
Solve for p:
-2 p - 4 = 2
Add 4 to both sides:
(4 - 4) - 2 p = 4 + 2
4 - 4 = 0:
-2 p = 2 + 4
2 + 4 = 6:
-2 p = 6
Divide both sides of -2 p = 6 by -2:
(-2 p)/(-2) = 6/(-2)
(-2)/(-2) = 1:
p = 6/(-2)
The gcd of 6 and -2 is 2, so 6/(-2) = (2×3)/(2 (-1)) = 2/2×3/(-1) = 3/(-1):
p = 3/(-1)
Multiply numerator and denominator of 3/(-1) by -1:
Answer: p = -3
(a) Kellie’s minutes-per-mile pace was faster than Ashley’s minutes-per-mile pace.
True
10/75 = 0.14
15/120 = 0.13
(b) Kellie ran 8 mph.
True
10 ÷ 1.15 = 8
(c) Ashley ran 12 mi in 90 min.
False
Speed = 7.5 mph
7.5 × 1.5 = 11.25 mi
