Volume is actually pretty simple once you get the hang of it, it’s just Base x Width x Height. So I’m this problem, all you would have to do is multiply these numbers BUT since it’s a triangle you’re going to divide that by two. So… 12 x 7.5 x 10 = 900 and then we dive by 2. 450. Hope this helps :)
Answer:
8t^3-36t^2+54t-27
Step-by-step explanation:
(2t-3)^3
(2t-3)(2t-3)(2t-3)
Multiply the first two terms
(4t^2 -6t -6t+9)(2t-3)
Combine like terms
( 4t^2 -12t +9) ( 2t-3)
Multiply
2t*( 4t^2 -12t +9) -3 ( 4t^2 -12t +9)
Distribute
8t^3 -24t^2 +18t-12t^2 +36t-27
Combine like terms
8t^3-36t^2+54t-27
A) 3:11
b) 11:8
this should be correct
