0.5(x^4 − 9) + 17

combine like terms.

Hello from MrBillDoesMath!

0.5 x^4 + 12.5

Discussion:

Only the constant terms are "like" and can be combined. Nothing combines with x^4.

0.5 ( x^4 - 9) + 17 =

0.5 x^4 -  0.5 (9) + 17 =               as 0.5(9) = 4.5

0.5x^4  -  4.5 + 17 =

0.5 x^4 + 12.5

Thank you,

MrB

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
