Answer:

z = 49

Step-by-step explanation:

z - 42 = 7

z - 42 = 7

   +42  +42

z = 49

1. add 42 to both sides (adding because its - 42)

2. that leaves us with 7+42 = 49 so z=49

to check your answer u can always plug in 49.

49 - 42 = 7

yup. 49-42 does equal 7.

Rudiy27
Since there is no picture shown, I just plotted the given data points myself. That is shown in the attached picture. The blue rectangle is rectangle PQRS while the orange one is rectangle JKLM. I believe there are some choices for this question but you forgot to include. Nevertheless, I will give my observations from the given figure. 

The tile PQRS is bigger than tile JKLM. A rectangle is a two-dimensional shape that has two sets of equal parallel planes. Thus, its area is equal to the length multiplied by its width.

tile PQRS = (9-5)*(12-7) = 20 units²
tile JKLM = (6-4)*(10-5) = 10 units²

Tile PQRS is larger by 10 units².
