If the area rectangle below us 39 square feet find the x value

x=5 and x=-11

Step-by-step explanation:

(x-2)(x+8)=39

Subtract 39 from both sides

Factor:

(x-5)(x+11)=0

Set factors to 0.

x-5 =0

x+11 =0

x=5, x=-11

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
