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

Answer:
Step-by-step explanation:
hello :
B. (x − 4)(x + 9)
calculate : (x − 4)(x + 9)= x²+9x-4x-36 = x²+5x-36
Answer:
5/8 < 7/12
Step-by-step explanation:
To find which is greater we can turn them into a decimal..
5/8 ⇒ 0.625
7/12 ⇒ 0.583
Then, we compare the two decimal numbers to get the answer.
0.625 is greater than 0.583.
Therefore, 5/8 is greater than 7/12 .
