Consider, please, the suggested solution.
Answer:
D. 2.
Step-by-step explanation:
Using the points (1,3) and (-1,-1):
The slope= (3 - -1) / (1 - -1)
= 4/2
= 2.
<span>f(x)=2x+1 and g(x)=x^2-7
(f+g)(x) = </span>2x + 1 + x^2 - 7
(f+g)(x) = x^2 + 2x - 6
answer
x^2 + 2x - 6
Answer:
the value of x=9 and AB(h)=9.396
A = L * W........x = W
L = 2x + 3
A = 119
119 = x(2x + 3)
119 = 2x^2 + 3x
2x^2 + 3x - 119 = 0
(2x + 17)(x - 7) = 0
2x + 17 = 0
2x = -17
x = - 17/2 or - 8.5....wont work because it is negative
x - 7 = 0 L = 2x + 3
x = 7 L = 2(7) + 3
L = 14 + 3
L = 17
so the width (x) = 7 inches and the length (L) = 17 inches...
the equation used was : 119 = x(2x + 3)...or 2x^2 + 3x - 119 = 0...not sure which equation they want...but they are the same
