Answer:
Step-by-step explanation:
Using FOIL (First, outer, inner, last)
First, we multiply 3x and x to get (First)
We then multiply 3x and 1 to get (outer)
Then 4 and x to get (Inner)
Then multiply 1 and 4 to get (last)
Since the quadratics are all positive, we add all the terms together to get:
. Since 3x and 4x are like terms, we add them together and simplify to get:
And since we can't simplify any further, that's our answer!
Hope this helps :D
Keep in mind I've never actually attempted this kind of problem.
Calculate how far both planes are after 2.5 hours
450 × 2.5 = 1125
350 × 2.5 = 875
The legs of the triangle will be 1,125 miles & 875 miles.
1125² + 875² = 2,031,250
Plane A is 1,425 miles from Plane B.
