A. The perimeter of a right triangle is given by summing all the sides.
4x + 2 + 7x + 7 + 5x - 4
x + 3 + 2x - 5 + x + 7
b. I think you have to combine like terms of the expressions.
16x + 5
4x + 5
c.
Large triangle: 4(3) + 2 + 7(3) + 7 + 5(3) - 4 = 12+2+21+7+15-4 = 53
Small triangle: 3 + 3 + 2(3) - 5 + 3 + 7 = 3+3+6-5+3+7 = 17
17% because you would do the number of times it landed on section a (14) over the total times spun (84) which gives you 16.6666 (16 2/3) which would round up to 17%. Hope this helps!
Answer: I think it’s the first one.
Step-by-step explanation:
Answer:
6 hours
Step-by-step explanation:
speed = distance/ time
6000meters to km = 6000/1000= 6km
speed for the first race = 6/2
speed = 3km/hr
for the second race
speed = distance/time
3 = 18/time
cross multiply
3* t = 18
divide both sides by 3
t = 18/3
t = 6 hours
