F2=(x-4)(x+4) = 0
the x-intercepts at (4,0) and (−4,0)
Answer :
1,173.04
Explanation:
Use the compound interest formula which is P(1 + r/n)^(nt) and plug in your numbers:
1000(1+0.02/4)^(4•8)
3 because the numbers for x are all different
Factors of 40: (1, 40) (2, 20) (4, 10) (5, 8)
---Using these factors will help us find a pair that adds up to -13 and multiplies to equal 40
-5 + -8 = -13
-5 x -8 = 40
(v - 8)(v - 5)
The trinomial can be factored into the following expression (v - 8)(v - 5).

Area of rectangle = length × width
300 = (x+10) × x
300 = 10x + x^2
Now we have the equation y=x^2 + 10x - 300
We can factor this equation to get our zeroes, which are:
-5(1+sqrt(13)),
5(sqrt(13)-1)
We only use the positive zero because we can't have a negative dimension.
Your width would be:
5(sqrt(13)-1)
Your length would be:
5(sqrt(13)-1) + 10
