Answer: x = 10

7x + 5 is equal to 9x - 15 because they have and share similar angles and verticies.

7x + 5 = 9x - 15

subtract 7x and and 15 to both sides. This leaves us with.

20 = 2x

Divide both sides by 2 to get x alone.

10 = x

Plug x back into original equation to check work.

7 (10) + 5 = 9 (10) - 15

70 + 5 = 90 - 15

75 = 75

Complete the square to make a perfect square trinomial. Then, write the result as a binomial squared.

Tatiana [17]

Answer:

Take the coefficient of ''n'', divide it by 2, and raise it to the second power;

$n^2+n+(\frac{1}{2})^2$

$n^2+n+\frac{1}{4}=0$

$=(n+\frac{1}{2} )^2$
