Question

If 2(x+5)=7x-5, then what is the value of 2X squared +10

Answer 1

Answer:

28

Step-by-step explanation:

in order to evaluate for the value of x from this 2(x+5)=7x-5 , we will open the bracket and the evaluate for x.

solution

2(x+5)=7x-5

2x + 10 = 7x - 5

collect the like terms together

2x + 10 +5 = 7x

15 = 7x - 2x

15 = 5x

divide both sides by 5

15/5 = 5x/5

3 = x

x =3

so, to evaluate for 2x² + 10

will be

2x² + 10

2 (3)² + 10

2 x 9 + 10

18 + 10
