Question

In order for the parallelogram to be a rectangle x=

Answer 1

Answer:

X is equal to 2

Step-by-step explanation:

90 = 13x + 34 + 10x + 10

Combine Like Terms:

90 = 23x + 44

Subtraction Property of Equality:

90 - 44 = 23x + 44 - 44 ---> 46 = 23x

Division Property of Equality:

46 ÷ 23 = 23x ÷ 23 ---> 2 = x

Check Your Work:

90 = 13x + 34 + 10x + 10

Fill In Variables:

90 = 13(2) + 34 + 10(2) + 10

90= 26 + 34 + 20 + 10

90 = 60 + 30

90 = 90

Answer 2

Answer:

x = 2

Step-by-step explanation:

Set the two equations 13x+34 and 10x+10 together to add up to 90 on the right which should look like this 13x + 34 + 10x + 10 = 90.  Combine the two x-values to get 23x and the two other numbers to get 44.  Your equation should now be 23x + 44 = 90.  Subtract 44 on both sides to get this equation 23x = 46.  Divide 23 on both sides to get your x value which is 2.
