B. 75
First you find the area of the triangle:
(base x height)/2
(3 x 5)/2
15/2
7.5
Then you multiply by the length of the prism (10):
7.5 x 10 = 75

Answer:
k^2/25
Step-by-step explanation:
(1/5k)^2
(k/5)^2
k^2/5^2
k^2/25
5x^2+8x+3=0
factor
(5x+3) (x+1)=0
using the zero product property
5x+3 =0 x+1 =0
5x=-3 x=-1
x=-3/5 x=-1
