Answer:

Yes one pair of the opposite sides could measure 10 inches , and the other pair could measure 13 inches.

Step-by-step explanation:

A parallelogram have opposite sides parallel and congruent

the given quadrilateral is a parallelogram then

10 = x + 2 Equation A

x + 5 = 2x - 3 Equation B

<u>Solving for Equation A:</u>

x = 10 -2 = 8 inches

<u>Solving for Equation B;</u>

2x - x = 5 + 3

x = 8 inches

<em>Value X are the same equations.</em>

<em>Means that </em>

<em>For x=8 inches opposite side</em>

<em><u>So Yes one pair of the opposite sides could measure 10 inches , and the other pair could measure 13 inches.</u></em>

What are some Solutions to the linear equation?: 3x+y=-8
svetlana [45]

9514 1404 393

Answer:

  (0, -8), (1, -11), (-1, -5)

Step-by-step explanation:

It is convenient to solve for y and choose values of x.

  y = -3x -8 . . . . . subtract 3x from both sides of the equation

Now, any integer value of x you choose will result in an integer value of y. Often, it is convenient to choose values near zero.

  x = -1, y = -3(-1) -8 = 3 -8 = -5 . . . . solution: (-1, -5)

  x = 0, y = -3(0) -8 = -8 . . . . solution: (0, -8)

  x = 1, y = -3(1) -8 = -11 . . . . solution: (1, -11)
