Answer:

Step-by-step explanation:

JL = JK + KL

84 = 3x+5 + 6x+7

Combine like terms

84 = 9x +12

Subtract 12 from each side

84-12 = 9x+12-12

72 = 9x

Divide by 9

72/9 = 9x/9

8 =x

We want KL

KL = 6x+7

6*8 +7

48+7

Lie is solving the quadratic equation by completing the square.

wel

we have

$3x^{2} + 18x - 8 = 0$

Step $1$

Move the constants to the right side

$3x^{2} + 18x = 8$

Step $2$

Factor 3 out of the variable terms

$3(x^{2} + 6x) = 8$

Step $3$

Add $27$ to both sides of the equation

$3(x^{2} + 6x+9) = 8+27$

$3(x^{2} + 6x+9) = 35$

Step $4$

Write the polynomial as a binomial squared

$3(x+3)^{2} = 35$

therefore

the answer is

Factor 3 out of the variable terms.
