Formula for Perimeter is P=2l+2w. Then you plug in the information that you already know:
P=2(x+6)+2(12)
64=2x+12+24
64=2x+36
28=2x
x=14
you plug x back into your equation for l and get l=14+6=20
The length is 20 ft.
Since the x value can be changed to anything other than 4 (because then you would be dividing by 0 in x-4), the answer is: All real numbers except 4.
To simplify this expression would be 4x-3
86 opposite of it so it would be87
Answer: slope intercept is y=mx+b
standard form is Ax+By=C.
point slope form is y-y₁=m(x-x₁)
so y=2/3x+2 is slope intercept
