X(x+5)+7(x+5) Help please its for algebra class thanks for your support and your help thanks a lot

Step-by-step explanation:

Let's simplify step-by-step.

x(x+5)+7(x+5)

Distribute:

=(x)(x)+(x)(5)+(7)(x)+(7)(5)

=x^2+5x+7x+35

Combine Like Terms:

=x^2+5x+7x+35

=(x^2)+(5x+7x)+(35)

=x^2+12x+35

=x^2+12x+35

step-by-step explanation:

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
