Answer:
The zeros are {-2, 3}
Step-by-step explanation:
Set each of these factors equal to zero, in turn, set each factor = to 0 and solve the resulting equation for x:
x + 2 = 0 yields x = -2;
x - 3 = 0 yields x = 3
The zeros are {-2, 3}
Each tricycle has 3 wheels and one seat, so the ratio of seats to wheels is 1:3
Recall your d = rt.
so hmm is about the same as the other one... so say the boat has a speed rate of "b", well, going downstream the boat goes say " b + 2 ", because the current is adding to it, and going upstream is " b - 2 " because the current is eroding from it.
So if the whole trip took 14 hours, say it took "t" hours going upstream, then going downstream it took the slack or " 14 - t ".
Also notice, the trip forth and back is the same 45 miles.

Answer: 35 seventh graders
Step-by-step explanation:
The simplified ratio is 4:7 sixth graders to seventh graders
The number of sixth-graders is 5 times the number shown in the ratio of attendees (20/4 = 5). Thus, the number of 7th graders must also be 5 times greater than the simplified ratio.
7*5 = 35, thus there are 35 seventh graders in the club
