Factor out 4
4(x^2 + 2x - 15)
to factor the equation inside the parenthesis, find two numbers that multiply to -15 and add to 2
those numbers are: 5 and -3
the answer is: 4(x+5)(x-3)
Answer:
1. -x+12=8 =-x=8-12-= -x=-4 dbs= 4/x
I got 224. 7(4)^2 = 112 •2 =224
Answer: C
Step-by-step explanation:
This describes an expotential function
At t = 0, P = 70
Therefore, C = 70
P = 70 e^kt
Solve for k by plugging in (4,360)
k = 0.4094
plug in t(7 hours)
70 e^(0.4094*7)
The answer roughly equals C
Answer: 2nd answer
