Pls help me someone pls can you show your work

If we split this figure into a rectangle and triangle, we can solve:

THe rectangle would have an area of 4.14 (a=b x h) and the triangle would have an area of 8.28 (a=1/2bh)

If we add these numbers together we should have the area

a=4.14+8.28

a=12.42

Step-by-step explanation:

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
