Yes it would be a triangular prism
w=37
2w+w+69= 180 knowing that all triangles add up to 180 form an equation
3w+69=180 combine like terms and subtract 69 from both sides
3w=111 divide by 3 from both sides
w=37
Answer:
The cost to fill the new family size box will be 
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z-----> the scale factor
we have

so

To find the new cost multiply the original cost by the scale factor elevated to the cube

The new volume would be

Answer:
5x² - 11x + 10
Step-by-step explanation:
(8x² - 4x + 1) - (3x² + 7x - 9) =
8x² - 4x + 1 - 3x² - 7x + 9 =
5x² - 11x + 10
