The volume of the prism is 
Step-by-step explanation:
First let's get the area of the triangle. To get that, we use the formula 
In words, this is <em>base · height ÷ 2</em>
When we plug in the numbers, it is 10 · 10 ÷ 2, which is equal to 50.
And of course we multiply 50 by 25 to find 
Answer:
It is not correct.
Step-by-step explanation:
If you plug 4 in for x, you get -2*4+5=13. This simplifies to: -8+5=13. This is an untrue statement since -8+5 is actually -3, not 13.

Answer:
Area of parallelogram: 1/2×h×sum of base lengths

Area = 1/2×4×(9+9)
= 36 cm^2
Answer:
-6 and 7
Step-by-step explanation:
It is useful to look at the factor pairs of -42.

Sums of these factor pairs are 41, 19, 11, 1.
You want the last pair of factors: -6 and 7.
