3x+2x+4=39 multi steps equation

x = 7

Step-by-step explanation:

3x+2x+4=39

combine like terms 3x and 2x: 5x+4=39

subtract 4 on each side to get x alone: 5x=35

divide 5 on each side to get x alone: x = 7

x = 7

i hope this helped :))

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
