I believe the answer is 4.50
Answer:
Step-by-step explanation:
30 = -5(6n + 6)...distribute the 5 thru the parenthesis
30 = -30n - 30....add 30 to both sides
30 + 30 = -30n
60 = -30n....divide both sides by -30
-60/30 = n
-2 = n <===

Answer:
After 10 weeks: 40 inches
Step-by-step explanation:
Equation
15 + 2.5w = h
15 = beginning height
2.5 = rate per week
w = weeks passed
h = total height
(x+6)(x+8) = 0
x = -6 or x = -8
I'm just wondering, does the equation happen to be 2x^2 + 14x + 48? That would make more sense with the answer I got.
