Zohar is using scissors to cut a rectangle with a length of 5x – 2 and a width of 3x + 1 out of a larger piece of paper. The per
imeter of the rectangle is 2(5x – 2) + 2(3x + 1). If x = 4 centimeters, what is the total distance Zohar needs to cut with the scissors? 31 centimeters
36 centimeters
62 centimeters
70 centimeters
Solution: From given perimeter = 2(5x-2) + 2(3x+1) Perimeter is the same as adding all the sides of the polygon. In this case, adding all sides of rectangle in terms of length. Therefore; 2(5 × 4 - 2) + 2(3 × 4 + 1) 2(20 - 2) + 2(12 + 1) 2(18) + 2(13) 36 + 26 =62 Therefore, 62 centimeters would be the answer.
It will be c- 20: 4q and 2(q+30) have to equal the same therefore q=30 which makes both these equations equal. 3p + 4q then have to equal 180 as they are on a straight line so you know q=30 so 4x30=120 so 180-120=60 Then 60/3=20 and that is your answer. Hope this helps :)
