Answer:
9x^2-3x+4
Step-by-step explanation:
(3x^2+2x^2-5x+7)+(4x^2+2x-3)
5x^2-5x+7+4x^2+2x-3
5x^2+4x^2-5x+2x+7-3
9x^2-3x+7-3
9x^2-3x+4
Answer:
n = -21/4 <em>or </em>-5.25
Step-by-step explanation:
(f+g)(x) = f(x) + g(x) = (|x| + 9 ) + (-6) =
|x| + 9 - 6 = |x| + 3
Answer is |x| + 3
Answer:
w = 2, EF = 30 , FG = 42
Explanation:
We have EF = 5w + 20 and FG = 7w + 28
Since these points E, F and G are col-linear points we have.
EG = EF + FG
And given that EG = 72
So, EF+EG = 72
5w + 20 + 7w + 28 = 72
12w + 48 = 72
12 w = 24
w = 2
So EF = 5w + 20 = 5x2 + 20 = 30
FG = 7w + 28 = 7x2 + 28 = 42
