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
Answer:
7x2 + 4 x + 20
Step-by-step explanation:
Subtract 3x2 from 10x2.7x2+10x+20−6xSubtract 6x from 10x.7x2+4x+20
The experimental probability of letter E is: 3/25
Step-by-step explanation:
The given diagram is the number of outcomes for each letter is given
We have to find the total number of outcomes for finding the experimental probability of letter E
So,
Total outcomes = n(S) = 5+12+8+10+6+9 = 50
Number of outcomes for Letter E = n(E) = 6
So the experimental probability will be:

Hence,
The experimental probability of letter E is: 3/25
