2t^2+1
Subtract t^2 from 3t^2 you get 2t^2
which is 2t^2+1 answer
Answer:
90 inches cubed
Step-by-step explanation:
The formula for the volume of a pyramid is (lwh)/3, with l=length, w=width, and h=height.
V = (lwh)/3
= (5*3*18)/3
= 5*18 = <u>90 inches cubed</u>
Given:
line C: y = x + 14
line D: y = 3x + 2
(6,20) or (3,11)
line C: y = 6 + 14 = 20 or y = 3 + 14 = 17
line D: y = 3(6) + 2 = 18 + 2 = 20 or y = 3(3) + 2 = 9 + 2 = 11
(6,20), because both lines pass through this point.
