omeli [17]

Answer:

Step-by-step explanation:

find the slope

\frac{4-8}{-5-(-3)} =\frac{-4}{-2} \\\\slope=2\\y=mx+b\\y=2x+b\\

take a coordinate to fill in

(-5,4)\\y=-5\\x=4\\-5=2(4)+b\\-5=8+b-8   -8\\-13=b\\

this means that the equation is y=2x-13

and if you add m and b

you get :-11

X=<br> Length=<br> Width=<br> WILL GIVE BRAINLIEST + 5 star
babymother [125]

Answer:

x = 20

Length = 20ft

Width = 12ft

Step-by-step explanation:

A = 240

x^2 - 8x = 240

x^2 - 8x - 240 = 0

x^2 - 20x + 12x - 240 = 0

x(x-20) + 12(x-20) = 0

(x+12)(x-20) = 0

x = 20

x = -12 (which we discard since x is a length)

So the dimensions are 20ft and 20-8 = 12ft
