Hello from MrBillDoesMath!
Answer: 3x^3 + 6 x^2 - 12 x (the third choice)
Discussion:
(x^2 + 2x -4) * (3x) =
x^2 (3x) + 2x (3x) -4 (3x) =
3x^3 + 6 x^2 - 12 x
which is the third choice
Thank you,
MrB

Answer:
7,24,18
Step-by-step explanation:
perimeter of a triangle = a₁ + a₂ + a₃
A/Q
let, 2nd side = x
then, 1st side =x-17
3rd side = x-6
perimeter= 49
.:
49 = (x-17)+ x + (x-6)
49 = x-17+x+x-6
49 = 3x -23
3x = 49+23
3x = 72
x = 72/3
x= 24
.:
1st side = (x-17) = 24-17=7
1st side= 7
2nd side = x = 24
3rd side = x-6
=24-6
=18
3rd side = 18
on calculating perimeter = 7+24+18=49.
Hope it helps:)
