P= 12 + 4x^2 - 2 + x^2 + 3x^2
Combine like terms
12-2= 10
4x^2 + 3x^2 + x^2= 8x^2
P= 8x^2 + 10
Sorry if this isn't right but this is what I think you would do
Answer:
42.3°
Step-by-step explanation:
Use SOH-CAH-TOA (O=opposite, A=adjacent, H=hypotenuse) we see that they give us the angle missing, x, but we first need to identify what method to use. They give us the opposite side from the angle, and they also give us the adjacent side from the angle, so TOA=tan.
now plug it in, since there is no angle then we plug it in as 
in the calculator, (be sure to be in degree mode)
x= 42.3°
(does that make sense)
Answer:
I think the answer was 33%.

Answer:
The value of X is 11
X=11
Step-by-step explanation:
Isolate the variable by dividing each side by the factors that don't contain the cariable.
