Answer:
Length: 20, Width: 14
Step-by-step explanation:
(x-12)(x-18)
x^2-30x+216=280
x^2-30x-64=0
x=32,-2
Plug 32 into x, and see if it equals 280
Answer:
−9
Step-by-step explanation:
(3)(4) (−3/4)
=12(−3/4)
-9
2r2+2r−24=0
Step 1: Factor left side of equation.
2(r−3)(r+4)=0
Step 2: Set factors equal to 0.
r−3=0 or r+4=0
r = 3 or r = −4
Answer:
y = 6x-4
Slope = 6
Since the line is perpendicular slope = -1/6
Equation of the line is
y +3 = -1/6(x-1)
Multiply through by 6
6y +18 = -x + 1
6y = -x -17
Hope this helps.
