I don't remember the names of the theorems at all, but we know that AD ≈ DE ≈ EB (Segment Addition). Which means <ACD ≈ <DCE ≈ <ECB (not completely sure how to prove this). Therefore, <1 ≈ <2. (Don't forget to state that <1 ≈ <ACD and <2 ≈ <ECB). With this and Angle Addition, we know that <ACE ≈ <DCB, so with SAS Congruence Theorem, we can prove ΔACE ≈ ΔBCD.
Hope that helps
Answer:
37
Step-by-step explanation:
first you need to add 1 plus 4 which is 5. then square it so it becomes 25. Then using order of operations do 6 times 2 which is 12 and add it to 25 to get 37.
Answer:
-4x + 12 = 20 is incorrect. she added 12 to 20 instead of subtracting 12 from both sides.
Step-by-step explanation:
It should have been, write problem
-4(x - 3) = 20
Use distributive property.
-4x + 12 = 20
subtract 12 from each side
-4x =8
divide each side by -4
x = -2
Answer:
$1.35 will be your answer
Step-by-step explanation:
18 x 0.075 = 1.35
(4a + 6b) x (2a - 2b)
the answer would be 8a2 + 4ab - 12b2
