X2-2xy-24y2
factor the trinomial

The factored form is (x + 4y)(x - 6y)

Step-by-step explanation:

In order to find this, we need to look for factors of the last coefficient (-24) that add up to the middle coefficient (-2). To do this, we list out the factors of -24.

-24:

1, -24

-1, 24

2, -12

-2, 12

3, -8

-3, 8

4, -6

-4. 6

The numbers 4 and -6 satisfy those criteria. So we put them in the parenthesis together with x as the first term and a y attached to our found coefficients.

(x + 4y)(x - 6y)

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
