Answer:
-2-2√3, -2+2√3
Step-by-step explanation:
Let x represent one of the numbers. Then the other number is -4-x. We want the product to be -8:
x(-4-x) = -8
-4x -x^2 = -8 . . . . . eliminate parentheses
x^2 +4x = 8 . . . . . . multiply by -1
x^2 +4x +4 = 12 . . . add 4 to complete the square
(x +2)^2 = 12
x +2 = ±√12 = ±2√3
x = -2±2√3
The two numbers are -2-2√3 ≈ -5.4641, and -2+2√3 ≈ 1.4641.
Answer:
5
Step-by-step explanation:
Maurissa has 1965 stickers, she wants to divide them equally into 8 bags
Therefore the amount of stickers that will be left after seperating them into the bags can be calculated as follows
= 1965/8
= 245 remainder 5
Hence the amount of stickers that will be left is 5
Answer:
Prime Numbers 2, 3, 5
Divisible by 2 - 2, 4, 6
One is NOT a prime number.
So, there are 5 out of 6 numbers that are even or are prime.
This leaves only 1 number that isn't.
So, the probability is 5/6 that the number rolled will be prime or even.
