Isolate the x in both cases. What you do to one side, you do to the other.
11x + 4 < 15
Subtract 4 from both sides
11x + 4 (-4) < 15 (-4)
11x < 11
isolate the x, divide 11 from both sides
11x/11 < 11/11
x< 1
x < 1 is your answer for the first one

Again, isolate the x.
12x - 7 > -25
Add 7 to both sides
12x - 7 (+7) > -25 (+7)
12x > -18
Isolate the x, divide 12 from both sides
12x/12 > -18/12
x > -1.5 is your answer for the second one.

Answer:
p(x) = (5x - 1) (x + 4) (x - 2)
Answer:
x = 3/5
Step-by-step explanation:
After substituting each option into the equation, we find that the only option that makes the equation true is x=3/5, since 4/5 - 3/5 = 1/5.
2L + 2(L-6) = 68
2L + 2L -12 = 68
4L = 80
L = 20
The length is 20 in. and the width is 14 in.
Recall the Laplace transform of a second-order derivative,
and the transform of cosine,
Here, both 
, so taking the transform of both sides of
gives
