The perimeter of the rectangle below is 104 units. Find the length of side QR. Write your answer without variables.
S
R
2y - 1
QR = 0
Х
P
3y + 3

length of side QR = 19 units

Step-by-step explanation:

Perimeter of a rectangle = (2 × length) + (2 × breadth)

length = side PQ = side SR = 3y + 3

breadth = side QR = side SP = 2y - 1

》2×(3y + 3) + 2×(2y - 1) = 104

》(6y + 6) + (4y - 2) = 104

10y + 4 = 104

10y = 104 - 4 = 100

y = 100/10

y = 10

Length of side QR = 2y - 1

= 2(10) - 1

= 20 - 1

= 19 units

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
