Answer:
(x-3)(x-2)
Step-by-step explanation:
x^2 -5x+6
What two numbers multiply to 6 and add to -5
-3 * -2 = 6
-3 -2 = -5
(x-3)(x-2)
we have
----> inequality A
The solution of the inequality A is the interval ------> [-1,∞)
-------> inequality B
The solution of the inequality B is the interval ------> (-∞,7]
The solution of the compound inequality is
[-1,∞) ∩ (-∞,7]=[-1,7]
therefore
the answer in the attached figure
45 divided by 3= 15 then 15 times 4 =60 mph
