I NEED HELP! I need to find the value of x and round to the nearest tenth

Aline on the wall and a line on the floor are skew. always, sometimes, or never?

Find the value of the variable and the length of each secant segment.

Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x^2 - 8 = -6x a. –7.12, 1.12 b. 7.12, –1.12 c. 7.12, 1.12 d. –7.12, –1.12
