Answer:

1  hour and 12 minutes

Step-by-step explanation:

Let's say x = time it takes for the trains to be 204 miles apart.

Speed = Distance/Time,

Time = Distance/Speed,

x = 204/ (80 + 90) = 204/170 = 1 and 1/5 hours or 1  hour and 12 minutes

Given that the product of two positive integers is 44, and their least common multiple is 22, what is their greatest common divi
swat32

Answer:

2

Step-by-step explanation:

For any positive numbers a,b we always have the following identity:

a\cdot b=gcd(a,b)\cdot lcm(a,b)

(gcd(a,b) denotes the greatest common divisor between a and b, and lcm(a,b) denotes the least common multiple between a and b)

In our case, we are given that a\cdot b = 44 and that lcm(a,b)=22. Plugging that in into our identity, we get:

44=gcd(a,b)\cdot 22

And so solving for gcd(a,b):

gcd(a,b)=\frac{44}{22}=2

Using the function attached.<br> Find (f+G)(x)
sp2606 [1]

We have been given two functions f(x)=-8x^3+5x^2+7x+4 and g(x)=8x^3-2x+3. We are asked to find (f+g)(x).

We will use composite function property (f+g)(x)=f(x)+g(x) to solve our given problem.

(f+g)(x)=-8x^3+5x^2+7x+4+8x^3-2x+3  

Now we will combine like terms as:

(f+g)(x)=-8x^3+8x^3+5x^2+7x-2x+4+3

(f+g)(x)=5x^2+5x+7

Therefore, the value of  (f+g)(x) would be 5x^2+5x+7.
