Answer:
Step-by-step explanation:
Because midpoints were used to make similar triangles we can say
AC=2(DE)
5x+12=2(9x-20)
5x+12=18x-40
-13x+12=-40
-13x=-52
x=4
AC=5x+12
AC=5(4)+12
AC=20+12
AC=32
Answer:
10a-11b is ur answer
Step-by-step explanation:
combine like terms
8a+2a=10a
-7b-4b=-11b
(always make sure to but in alphabetic order)
10a-11b
