........Option C ) n × 2 = t
Answer:
7 cm, 16 cm, 19 cm
Step-by-step explanation:
Let s represent the length of the shortest side in cm. The longest side is 3s-2, and the other side is 2s+2. The perimeter is the sum of the side lengths.
P = s + (3s -2) +(2s +2)
42 = 6s . . . . . simplify, use the given value of perimeter
7 = s . . . . . . . divide by 6
2s+2 = 16
3s -2 = 19
The side lengths are 7 cm, 16 cm, and 19 cm.
U have to rearrange to find x.
So first u look at the equation and u see u have to - 29 as u have to get x on its own.
This leaves u with:
6<3x
Now u have to divide by 3 to finally get x on its own, so this would leave u with the answer:
2<x
And the number line which represents this is B.
