Find the least common multiple of 4, 6, and 8
. Multiples of 4 are: 4, 8, 12, 16, 20, 24, 28, 32, 36
Multiples of 6 are: 6, 12, 18, 24, 30, 36
Answer:
no
Step-by-step explanation:
The set of perfect squares includes {0, 1, 4, 9, 16, 25, ...}.
Subtracting a couple of the elements, we get ...
4 - 1 = 3 . . . . not a member of the set
The set is NOT CLOSED under subtraction.
Answer:
Slope is -2
Step-by-step explanation:
(y2-y1) / (x2-x1)
(6-10) / (-10+12) = (-4)/(2) = <u>-2</u>
Answer:
(x-2)(x+4)
Step-by-step explanation:
So it would be A.
Explanation: The middle number is 2 and the last number is -8.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 2
Multiply together to get -8
Can you think of the two numbers?
Try -2 and 4:
-2+4 = 2
-2*4 = -8
Fill in the blanks in
(x+_)(x+_)
with -2 and 4 to get...
(x-2)(x+4)
Answer:
(x−2)(x+4)
