Answer:
b
Step-by-step explanation:
(x - 4) (x - 3)
x^2 - 3x - 4x + 12 (you distribute x in (x-4) to each of the terms x and -3 and multiply them. x*x is x^2 and x*(-3) is -3x. Then, you distribute -4 in (x-4) to each of the terms x and -3 and multiply them. -4*x is -4x and -4*-3 is 12)
x^2 - 7x + 12 (B)
Answer:
11/15
Step-by-step explanation:
If 4 out of 15 are Canadian, the ratio of the probability of picking a Canadian is 4/15. That means that the probability of NOT picking a Canadian is the complement of 4/15 which is 11/15. Therefore, the probability of not picking a Canadian is the same thing as the probability of picking an American penny which is 11/15.
Sense this string would only be 11 (in), and we are cutting it into 3 pieces, this would show us that we would then be dividing the 11 (in) string into 3 pieces. The expression would be below.
Sometimes when you’re doing math, it’s easier to line your numbers up when you have your ratio as a decimal! Hope it helped
Answer:
x = -10
Step-by-step explanation:
2(x + 3) = x - 4
2x + 6 = x - 4
2x - x = -4 - 6
x = -10
