Answer 1

Answer:

Then the width would be (x+9) and the length would be (x-1)

Step-by-step explanation:

If you factor the expression you get

$x^2 - 8x - 9 = (x+9)(x-1)$

Then the width would be (x+9) and the length would be (x-1)

Answer 2

Answer:

(x-1)  (x+9)

Step-by-step explanation:

Consider the form x2 + bx+c. Find a pair of integers whose product is c and whose sum is b In this case, whose product is  − 9 and whose sum is 8.
