Answer:
11v^2 - 8v + 1
Step-by-step explanation:
(4v^2 - 5v - 1) + (7v^2 - 3v + 2)
open brackets
4v^2 - 5v - 1 + 7v^2 - 3v + 2
place like terms together (remember signs remain same )
4v^2 + 7v^2 - 5v - 3v + 2 - 1
add or subtract like terms
11v^2 - 8v + 1
The answer would be 1:11, or 6:66. 1:11 is the simplified verison.
Answer:
31/30 or 1 & 1/30
Step-by-step explanation:
First we need to create a denominator divisible by 3, 5, and two. The lowest common denominator would be 30.
we need to make them all have this denominator, so, for example for one third we would have the equation 1/3 = x/30
in this case x = 10 to make the two fractions equal. Do this with the two other fractions to get 1/5 = 6/30 and 1/2 = 15/30
now all 3 fractions have a common denominator, so we can add them now.
10/30 + 6/30 + 15/30 = 31/30
