Answer:
= 3±2sqrt5
Step-by-step explanation:
(x-1)(x-5)=x^2-5x-x+5=16 (foil first outer inner last)
x^2-6x+5=16 move 16 over
x^2-6x-11=0 Using the quadratic formula
= 3±2sqrt5
So we need to put in the area of the rectangle which is 15 so let’s start
x+5+x+1=16
Collect the like terms
2x+5+1=16
Now you add the other numbers
2x+6=16
Now you subtract 6 by both sides
2x+6=16
-6 -6
Now you have left 2x=10 so divide 2 by both sides
Therefore the value of x is x=5
