Yes, you need to make the denominators the same. 2/3 becomes 8/12. So now you add 7/12 and 8/12, getting 15/12. But you're not done you need to simplify 15/12. The answer is 1 1/4.
Answer:
(6x + 5)(7x² - 6)
Step-by-step explanation:
Factor the first/second and third/fourth term
42x³ + 35x² - 36x - 30
= 7x²(6x + 5) - 6(6x + 5) ← factor out (6x + 5) from each term
= (6x + 5)(7x² - 6)
The combination formula is given by
C(n, r) =

C(11, 8) =

C(11, 8) = 165
So, there are 165 ways of choosing 8 flowers out of 11 flowers
Lets draw our triangle:
Lets use the "Law of Sines" to find our side r:

So r=18
26 miles/1 gallon. A unit reate is a rate with 1 in the denominator.
