Solve this equation -9-6+12h+40=22

a. h=24
b. h= -4/7
d. h= -4

Step-by-step explanation:

We have been given an equation . We are asked to solve our given equation.

First of all, we combine like terms as shown below:

Now, we will subtract 25 from both sides of our equation.

Upon dividing both sides of our equation by 12, we will get:

Therefore, the solution for our given equation is .

i think the length is 12 and the width is 17

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!
