Find the perimeter and area of the square

Perimeter of a square: side length * 4

Area of a square: side length²

{Plug in 16 in for the side length.}

Perimeter: 16 * 4 = 64 inches

Area: 16² = 256 in²

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
