Ihave no time and i need these ! 1. 5b + 2 = 17 2. 3/8 n + 1 = -25 3. 9 + 4b = 17 4. 8x + 7 = - 7 5. 4d - 35 = -3 6. 15a - 54 = -9

Question 1. 5b + 2 = 17

Step 1. Subtract 2 from both sides of the equation.

5b+2-2=17-2

Step 2. Then simplify.

5b=15

Step 3. Finally divide by 5.

5b/5=15/5

b=3

Question 3.

Step 1. Subtract 9 from both sides.

9+4b-9=17-9

Step 2. And simplify.

4b=8

Step 3. Finally divide by 4.

4b/4=8/4

b=2

Hope this helps! :)

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!
