For which value of x is the figure a rhombus? a. x = 6 b. x = 7.5 c. x = 12 d. x = 18.75

First keep in mind these two angles are equal to each other resulting in the equation needed to solve the answer has a = in it!

2x+39=6x-9

First subtract 2x from both sides ( 2x-2x and 6x-2x)

39=4x-9

Now add 9 to both sides (-9+9 and 39+9)

48=4x

Now divide both sides by four (4x/4 and 48/4)

x=12

The answer is x=12!

Hope this helped

Step-by-step explanation:

the answer would be c:   ax + b = ax + c

step-by-step explanation:

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
