d

Step-by-step explanation:

60

Step-by-step explanation:

if you look at it close the top shape is half of 12 so its 6 so nosubtract 6 from 18 and get 12 now add (18+12+6+6+12+6=60)

rounding to the nearest thousandth would be 452,000

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
