Answer:
A) 14
Step-by-step explanation:
Take the width: 6 and multiply it 3 times because it says triple.
That gives you: 6 * 3 = 18
Then subtract 4 because it says four inches less than.
That gives you: 18 - 4 = 14
Answer:
1/12
Step-by-step explanation:
There are 12 sides, and 7 is one of them. Therefore, there is a 1/12 chance of it landing on that side if it is a fair cube.
Answer:
255
Step-by-step explanation:
(1-15%)a=300
a=255
Answer:
n = -5, 3.
Step-by-step explanation:
n^2 + 2n - 15 = 0
Let's check if we can factor this quadratic:
We need 2 numbers whose product is -15 and whose sum is +2.
There are 2 such numbers and they are +5 and -3, so the factors are:
(n + 5)(n - 3) = 0.
n + 5 = 0 or n - 3 = 0
therefore the zeroes are -5 and 3.
