Answer:
560
Step-by-step explanation:
Step-by-step explanation:
x=√7+√5, y=√7-√5
therefore, xy = (√7+√5)(√7-√5) = 7-5 = 2.
Hope this helps you.
F(x) = 25 - 2x
f(5) is pretty much the value of f(x) when x = 5
Plug x=5 into f(x)
f(5) = 25 - 2(5)
= 15
That's your answer.
Have an awesome day! :)
Hi!
We will solve this using proportions, like this:
88 miles in 3 hours
x miles in 4 hours
________________
x = (88*4)/3
x = 352/3
x = 117,33 miles in 4 hours
Hope this helps!
