When adding or subtracting fractions, multiply to get the same denominator (bottom number).
When multipling two fractions, just multiply straight across, factor diagonally if possible.
When dividing fractions, flip the second fraction over and multiply.
For the polynomials, you just need to combine like terms.
3x + 4y² + 7x + 6y² = (3x + 7x) + (4y² + 6y²) = 10x + 10y²
You can factor this further but I don't know if its necessary.
= 10(x + y)
Let me know if you have any questions.
Answer: A
Step-by-step explanation: Ethan has a 1:6 ratio while Mia has a 1:7 ratio
Answer:
the answer is 9
Step-by-step explanation:
x=9 and w=9 making it 18, so if x=9 then v=7 because 7+9=16
144.4 is the answer when rounded of to the nearest tenth(1/10 or 0.1)
Answer:
4x
Step-by-step explanation:
the -8 and +8 cancel out
x and 3x are both positive so add them
you're left with 4x
