Answer:
x = 20
Step-by-step explanation:
3x + 26 = 2(3 + 2x)
~Simplify
3x + 26 = 6 + 4x
~Subtract 26 to both sides
3x = -20 + 4x
~Subtract 4x to both sides
-x = -20
~Divide -1 to both sides
x = 20
Best of Luck!

Answer:
A. x = 5 (Equation below)
B. AC = 9 | BD = 9
Step-by-step explanation:
A. Since we know the diagonals of an isosceles trapezoid are congruent, we know that the two bottom parts of the diagonal BD (2x - 8 and x - 4) are congruent to the diagonal AC (x + 2) . This means you can just equal them together and get the value of x:
2x - 8 + x - 4 = x + 2
3x - 12 = x + 2
3x = x + 14
2x = 14
x = 7
B. Just plug in 5 for x:
AC = x + 2 = 7 + 2 = 9
BD = 2x - 8 + x -4 = 3x - 12 = 21 - 12 = 9
