We subtract the 17 from the 981 to make the two sides even so it’s easier to calculate, 981 - 17 = 964, then divide that by 2, 964/2 = 482. So your answer is 482.

Answer:
what do you mean
Step-by-step explanation:
Answer:
7.
lateral surface area of traingular prism=perimeter of traingle ×length=[5+3+4]×6=72cm²
curved surface area=2[area oftraingle]=2×1/2×4×3
=12cm²
now
total surface area=72cm²+12cm²=84cm²
8.
volume of traingular prism=area of traingle ×length
=1/2×12×3.4×4=81.6cm³
Answer:
The answer
x=3
y=4
Step-by-step explanation:
You use substitution to solve it:
x+1=-2x+10
3x+1=10
3x=9
x=3
y=4
plug in the solution to the equation to verify your answer.
