Distribute invisible-1 to the 2x^2+4x-12
5x^2+3-2x^2-4x+12
group like terms
5x^2-2x^2-4x+3+12
3x^2-4x+15
14=A=Lw
L=2w-3
14=(2w-3)w
0=2w²-3w-14
0=(2w-7)(w+2)
7/2=w or w=-3
Measurements aren't negative
w=7/2 ft
L=2(7/2)-3
L=7-3
L=4 ft
Answer:
(- 2, 4 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) , then the midpoint is
( , )
Here (x₁, y₁ ) = A (4, 6 ) and (x₂, y₂ ) = B (- 8, 2 )
midpoint = ( , ) = ( , ) = (- 2, 4 )
