Let’s call the speed of the slower car S, then the speed of the other is S+10mph.
At 5pm they have been travelling for 3 hours. The slower car travels a distance 3S and the faster one 3(S+10).
But the two distances must add up to 240 miles so 3S+3(S+10)=240, 3S+3S+30=240, 6S=210, S=35 mph. The faster car’s speed is 45mph. We can see that 3S is the same distance as 3x, so x=S=35 mph, and the distance the faster car travels is 3×45=135 miles.
Easy
5th degree means highest power is 5 so must have x^5
trinomial means 3 terms
A. trinomial, highes power is 5, check
b. trinomial, highest power is 3, nope
c. not a trinomial, highest power is 3, nope
d. not a trinoial, highest power is 5, nope
answer is A
It is T because the sign in front of 50 means to square the number after it. So 50/2=25.
The thing with nasa is that when they use money to build and land things such as space rovers or space shuttles, the money that is used is put back into the economy instead of just floating in space. So the idea that its a waste could easily be debunked by the fact that the money that is used is still in the economy, whether or not you believe the exploration of space is needed could also be a solid point for your paper. Hope that I could help, Good luck with your paper
