PLEASE EXPLAIN AND PLEASE HELP ME AND EXPLAIN I NEED HELP

its right because

6 x 5 is the area of the leftmost rectangle

4 x 5 is the area of the bottom rectangle

3 x 5 is the area of the rightmost rectangle

5 x 5 is the area of the slanted square on the top

the last term is the area of the trapezoid, which is (base1 + base2) x height /2

they split the trapezoid thing into a square and a triangle, which gets you the same answer

they multiplied it by 2 because there are 2 trapezoids

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
