Answer:
3(x - 5)(x + 1).
Step-by-step explanation:
3x^2 - 12x - 15
Dividing through by 3:
= 3(x^2 - 4x - 5)
We need 2 numbers whose sum is -4 and whose product = -5. That is -5 and +1 , so the factors are:
3(x - 5)(x + 1).
So hmm notice the picture below
that's the 30-60-90 rule, notice your triangle, the bottom-left-angle is a right angle, 90°, the angle atop is 30°, so the angle on the bottom-right has to be 60°, thus is a 30-60-90 triangle, and as you can see on the triangle on the left in the picture, those are the ratios for it
so 8 will be x, what is the longer leg or side in yours then? well, is
Answer:
2628.48 cubic inches
Step-by-step explanation:
The inflatable raft has 4500 cubic inches of air inside it when fully inflated.
The inflatable raft loses air at a rate of a decrease 6.5% each day.
Now, we have to calculate the volume of air that will be left in the raft after 8 days.
Therefore, the volume of air left in the raft after 8 days will be
cubic inches. (Answer)
