Dafna11 [192]
In this problem, you have already shown the solution.

24 = 3y - 6 => 30 = 3y, y =10

12 = 5x + 2 => 10 = 5x , x = 2

And yes, basically parallel sides must have the same length

These are the answers:

for 17.) x = 2
y = 10

for 18.) mid segment = (side 1 + side 2) / 2 -->
19 = (24 + side2) / 2 -->
38 = 24 + side2,

thus, side 2 = 14 units

Mary and Jane have rectangular pools that are similar in shape. Mary’s pool dimensions are 2.1 times the corresponding dimension
Naddik [55]

Answer:

A

Step-by-step explanation:

Let's assume the first pool to have dimensions 3.0 by 2.0

The second pool being 2.1 times the first will have dimensions 6.3 * 4.2

The area of the first pool is 6.0 and that of the second is 26.46

making the area of the second pool 4.41 times that of the first.
