If you're looking for f(x)
then
g(x) = sqrt(4x + 4)
h(x) = sqrt(4x + 28)
h(x)-g(x) = 24
meaning that sqrt(24) must be the constant of f(x)
f(x) = x(sqrt(24))
h(x) = f(g(x)) = (sqrt(24))(sqrt(4x+4)) = sqrt(4x+4+24) = sqrt(4x+28)
The greatest common factor of 12 and 45 is 3. So its B. 12.
The answer is D.The triangles are similar by the SSS similarity theorem.
Answer:
40 miles
Step-by-step explanation:
the horse travels 10 miles an hour
1 hour = 10 miles
2 hours = 20 miles
3 hours = 30 miles
4 hours = 40 miles
or you could just do 10 x 4
hope that helps :)
Answer:
adult=10
Child=7
One adult and one child=10+7=17
Step-by-step explanation:
Let a be the price of an adult ticket
c = price of the child ticket
2a+4c = 48
5a+2c = 64
Multiply the second equation by -2 and add to the first equation
2a+4c = 48
-10a-4c = -128
---------------------
-8a +0c = -80
Divide by -8
-8a/-8 = -80/-8
a = 10
Now find c
2a+4c=48
2(10)+4c=48
20+4c=48
4c=48-20
4c=28
4c/4=28/4
c=7
