The rectangles A and B have perimeters of 94 cm and 56 cm as shown below.
2x cm
(x + 6) cm
А
3 cm
(y + 4) cm
Perimeter = 56 cm
Perimeter = 94 cm

step-by-step explanation:

d

step-by-step explanation:

i used the pitagoras theoreme

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
