What should be the first step to solve the equation?
2x + 9(x - 1) = 8(2x + 2)- 5

It should be to distribute the parentheses

Step-by-step explanation:

That equals 2x+9x-9 = 16x+16-5 = 11x-9+=16x+11. You should be able to go from there.

x=-4

Step-by-step explanation: distribute into the parenthesis

2x+9x-9= 16x + 16 -5

combine like terms

11x-9= 16x +11

add 9 on both sides

11x= 16x +20

subtract 16 on both sides

-5x=20

divide by -5 on both sides

x=-4  

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
