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

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
