Answer:
x = 8
Step-by-step explanation:
By AA similarity, ΔABD ~ ΔCDE. So, corresponding sides are proportional.
AB/BD = CD/DE
x/12 = 4/6
x = 12(4/6)
x = 8
First you distribute the six
-138>-36b+42
Then you subtract 42
-180>-36b
Next, you divide by -36 and since you are dividing by a negative, you turn the sign around
5
It's A
because it can be into a decimal and then to an equation
X=1 & Y=12
X=2 & Y=20
X=3 & Y=30
He is wrong...
2 1/2 + 3 3/5 = 97/20
Simplified, I believe the answer is 4 17/20
