Answer:
6X^2 -X -12
Step-by-step explanation:
(2X-3)(3X+4)
FOIL
first 2X*3X = 6X^2
outer 2X *4 = 8X
inner -3 *3X = -9x
last = -3 *4 =-12
Add them together = 6X^2 +8X -9X -12
= 6X^2 -X -12
The answer is the last one
I know that you need to use subtracting.
you also need the make the denominators the same.
Find what the LCM for both numbers 5 and 10.
5: 5, 10, 15
10: 10,20,30
Both have 10 and common.
Do 4/5 x 2/2 and you get 8/10.
Then do 2 1/10 x 1/1 and you get 2 1/10.
then subtract 8/10 by 2 1/10.
You will get 2 7/10 as your answer.
Answer: B
Step-by-step explanation:
Your answer would be 3/4 (three quarters).
-----------------------------------------------------------------------------------------------------------------
This can be simplified even further because both the numerator (6) and the denominator (8) can be divided by 2.
So-- 6 divided by 2 would be <u>3</u>, and 8 divided by 2 would be <u>4</u>. 3/4 cannot be simplified even further so this would be your final answer.
I hope this helped you out a bit :]
