Answer:

width =4.5ft

length=6ft

Step-by-step explanation:

w = x

L = 2x-3

area = L*w

27 = x(2x-3)

27=2x^{2} -3x

2x^{2} -3x-27=0

2x^{2} +6x-9x-27=0

2x(x+3)-9(x+3)=0

(2x-9)(x+3)=0

2x-9=0

2x=9

x=9/2

x=4.5

L=2x-3=2*4.5-3 =9-3=6

What is the slope of the line through the points (5, 5) and (3, -1)
soldier1979 [14.2K]

Answer: -0.33

Step-by-step explanation:

So how you would do this as you would set it up in a graph on a piece of paper you would take both points you'd use your slope formula, which is m=y2-y1 over x2-x1 And then you sell your formula with the numbers. So it would be 3-5 over 5-(-1) And then you subtract both of those and you take your two answers and divide them. -2÷ 6 =

Answer:

A = 1863

Step-by-step explanation:

There are a few ways you could do this but I will do the one I know best.

Keep in mind the area is the L(enght x W(idth) = A(rea)

There are two long rectangles if you cut off the square in the middle so find the area of those two first.

31 x 23 = 713

713 x 2 = 1426 (Did this to get the area for both of them.

Now find the area of the square.

23 x 19 = 437

The you would add them all up together to get 1426 + 437 = 1863

Hope this helps :)
