Answer:
The length is x + 5 inches
When x = 14, the width is 12 inches and the length is 19 inches.
The polynomial is x² - x - 12.
Step-by-step explanation:
(a) length : x+5
area= l×w
x^2+3x-10= l×(x-2)
(x+5)(x-2)=l×(x-2)
therefore (x-2) cancel out each other
then l = x+5
You can see that from (5,5), you go down 4 units are right 5 units, making the slope .
