You can change it to 130-70 and that'll give you 50.

Then just cross out the 0 from the 50 since 13-7 didn't have any zeros. So 5.

Please answer asap it's summer homework <br><br> Find the surface area of the prism.
Basile [38]
1. Area of triangle
1/2(10)(12)=60
There are two triangles, so multiply by 2
=120

2. Find area of the rectangles
This is an isosceles triangle, so the two rectangles are congruent
(2)(13)(3)=78

3. Find area of bottom rectangle
10(3)= 30

4. Add everything up
120+ 78 + 30= 228

Therefore the surface area of this prism is 228

I hope i helped :)

Pls help tap picture to see the three problems
valentinak56 [21]
1. Slope intercept form. First find two points to get slope: (0,-3) and (-3,-4). Slope is
(-4 - -3)/(-3 - 0)= 1/3
Use one of the points of (x,y) to solve for b
Y=1/3x + b
-3 = 1/3(0) + b
-3 = b so your slope intercept equation is
Y = 1/3x - 3

2. Rate of Change is slope. Your points are (0,10) and (24,6) so slope is (6-10)/(24-0)
= - 1/6 which means that for each 1 unit increase in x, y decreases by 1/6.

3. Standard form is ax + by =c
Notice it is the same line as in the first graph so it's the same equation
y = 1/3x - 3
First, you cannot have fractions, so you have to multiply the equation by 3 to get rid of the 1/3.
3y= x - 9. Now move the x over:
-x + 3y = - 9. Now get rid of the negative value on x by multiplying the entire equation by -1:
x - 3y = 9
