AC = 32
2x + 6x + 8 = 32 (plug in into equation)
8x + 8 = 32 (simplify)
8x + 8 (- 8) = 32 (-8) (subtraction of equality,)
(what you do to one side, you do to the other)
8x/8 = 24/8 (division of equality)
x = 3 (answer)
hope this helps
Exponential decay is given by the equation
F = P(1 - r)^t
0.5 = 1(1 - 0.092)^t
0.5 = (0.908)^t
log 0.5 = log (0.908)^t
log 0.5 = t * log 0.908
t = (log 0.5)/(log 0.908)
t = 7.18
Answer: 7.2 years
Answer:
x^2+7x+12
Step-by-step explanation:
(x+3) (x+4)
FOIL
first: x*x = x^2
outer: 4x
inner: 3x
last: 3*4 =12
Add them together
x^2 +4x+3x+12
x^2+7x+12
