Answer :
(x–30) (x-10)
Given equation :
• x² - 40x + A
when A = 300
1. Use the sum-product pattern
x²- 40x + 300
x²−10x−30x+300
2. Common factor from the two pairs
x² – 10x-30x+300
x(x−10)−30(x−10)
3. Rewrite in factored form
x(x−10)−30(x−10)
(x-30) (x-10)
Answer:
it is 105
Step-by-step explanation:
but I'm not 100% sure
Answer:
6
Step-by-step explanation:
Given : g(x) = and h(x)=2x-8.
g*h(x) =(2x-8).
We have square root(x-6) in composite function f*h(x).
So, we need to find the domain, we need to check for that values of x's, square root(x-4\6) would be defined.
Square roots are undefined for negative values.
Therefore, we can setup an inequality for it's domain x-6≥0.
Adding 4 on both sides, we get
x-6+6≥0+6.
x≥6.
Let us consider the initial position of train A, 
. This implies that 
.
Moreover, we have
This implies that the two equations are
The two trains meet if and only if their positions are the same, at the same time:
So, the two trains meet after 2 hours.
Answer:
31/1488 --> 1/48
Step-by-step explanation:
1. let 31/1488=x^-1
2. 31*x^-1=1488
3. 31*48=1488
