Answer: x = 6

Explanation:

P = 2(l + w)
56 = 2(3x + 10)
56 = 6x + 20
56 - 20 = 6x
36 = 6x
36/6 = x
6 = x

Therefore, x = 6

When you roll two number cubes, what are the odds, in simplest form, in favor of getting two numbers less than 4? A. 1:3 B. 3:1

AfilCa [17]

Answer:

1:4; C

Step-by-step explanation:

If you roll two cubes, they have 6 sides meaning 6 is the highest number. That's 2 more then 4 so I will subtract to two from each which makes it certain I will roll two dice less then 4. Removing two from each is 4 ergo the answer is 1:4
