Answer:
A) 7 is your answer.
Step-by-step explanation:
AD is congruent with AB, and because it is a kite, by definition, DC is congruent with BC. Set the two measurements equal to each other.
Set the two measurements equal to each other.
2x + 3 = 3x - 4
Isolate the variable x. Note the equal sign, what you do to one side, you do to the other.
First, subtract 3 and 3x from both sides.
2x (-3x) + 3 (-3) = 3x (-3x) - 4 (-3)
2x - 3x = -4 - 3
Simplify.
- x = -7
Isolate the variable. Divide -1 from both sides.
(-x)/-1 = (-7)/-1
x = 7
