The answer is: " (x − 8) (x + 3) " .
__________________________________________________________
" (x − 8) (x + 3) " are the factors of: " x² − 5x − 24 " .

Explanation:
__________________________________________________________
Given: "x² − 5x − 24 " ; Factor this "trinomial" expression completely.
We notice the "-5x" and the "-24 .
What factors of "-24" add up to "-5" ?
-1 + 24 ? No.
-24 + 1 ? no.
-12 + 2 = -10? No.
12 + (-2) = 12 - 2 = 10 ? No.
-3 + 8 = 5 ? No.
-8 + 3 = -5 ? Yes!
So: " (x − 8) (x + 3) " are the factors of: " x² − 5x <span>− 24 " .

Answer:
The area would be 40.5 cm ^2
Step-by-step explanation:
Well first you don’t gotta worry about some isosceles trapezoid thingy.
You just gotta know the formula for a trapezoid is (b1+b2)/2)h
B1 in this case is or base 1 (9 or 4.5)
b2 in this case is or base 2 (9 or 4.5)
(you can only choose one base for each)
ANd you add those 2 up and you’d get 13.5
13.5/2 which is 6.75
Now we multiply it by the height which is 6 and gte 40.5
40.5cm ^2 is the final answer
Your answer will be graphed as a parabola and the y intercept is (0,3) and the other coordinate would be (1,2) the parabola is a minimum
