You're basically multiplying the number and the variable with the number on the outside of the parenthesis.
So, 8(x + 7). You multiply 8 and the variable to get 8x. The same with '7'.
8 times 7 is 56.
Answers:
A) 8x + 56
B) 66 + 6x
C) 8x + 8
Answer:
B
Step-by-step explanation:
What is required is the probability of selecting one orange and one black kitten.
outcomes ( 1 O and 1B) = 4C1 * 5C1
Total outcomes = 9C2
Note: the order of color does not matter it is simply a matter of selection hence only combinations are made NOT permutations.
P (1O and 1B) = outcomes ( 1 O and 1B) / Total outcomes
P (1O and 1B) = (4C1 * 5C4) / 9C2 = 0.5556
Answer:
C
Step-by-step explanation:
So if x is the number, then 4 times the number would be 4x and adding that to -8 would be 4x + (-8) and then 12 times the number would be 12x, so you have 4x + (-8) = 12.
Then, solve:

subtract 4x from both sides

divide both sides by 8
