Answer: E. None of the above
Step-by-step explanation:
The equation to solve the problem should look like...2x = $2.91 / 3
Use the distributive property backwards.
xp+yp=z become p(x+y)=x, which solves to p=x/(x+y)
Answer: 14
Explanation: x + x + 2 + x + 4 = 42. x = 12. 12 + 2 = 14. I don’t really know how to explain it on words
This is the difference of two perfect cubes.
(6y-4)(36y^2+24y+16)
Given:
Net of a triangular prism
To find:
Which equation can be used to calculate the surface area of the triangular prism.
Solution:
Using formulas:
Area of rectangle = length × width
Area of triangle = 
Area of left triangle = 
Area of right triangle = 
Area of bottom = 5 × 10
Area of Middle = 12 × 10
Area of top = 13 × 10
Surface area of triangular prism:
Surface area = Area of left triangle + Area of right triangle + Area of bottom + Area of middle + Area of top

Replace multiplication by brackets.

The equation can be used to calculate surface area of triangular prism is
.
