3(t + 4) - 2(2t + 3)= -4

T=10

Step-by-step explanation:

3(t + 4) - 2(2t + 3)= -4

3t+12-4t-6=-4

-t+6=-4

-t=-10

t=10

Answer choice d

Step-by-step explanation:

To find the volume of this triangular prism, you first need to find the area of the triangular base. The formula for the area of a triangle is bh/2, which in this case is 3*2/2=3 square units. Multiplying this by the height of the prism, 3.5, you get a total of 10.5 cubic inches, or answer choice d. Hope this helps!
