Simple...
you have: (-2,20) and (3,-10,)
Using

to find slope--->>>

=-6
m=-6
Using y=mx+b to find the equation of the line-->>>(Use any of the coordinates)
(-2,20)
20=-6(-2)+b
20=12+b
20=12+b
-12 -12
8=b
y=-6x+8
Thus, your answer.
A. 81 because the formula for surface area is 2(wl + hl + hw)
So the formula filled in is 2( 1 1/2 x 3 + 2 x 3+2 x 1 1/2 ) = 27
and 27 x 3 = 81
Answer: the answr is b because its divisble
Step-by-step explanation:
So you're using the Pythagorean theorem which is a^2 + b^2 = c^2... so if you dont have b you can manipulate the equation. That equation is c^2 - a^2= b^2, so you square 47 which is 2209 and then square 13 which is 169... you do 2209-169 and that equals 2040, then you do the square root of that which is 45.166359 that can be simplified to 45 or two decimal points 45.167. Hope that Helped! :)
