Answer:
Step-by-step explanation:
1. 3x2 + 5x - 4 + 6x2 - x + 7
= combining like terms
= 9x2 + 4x + 3
2. 2y2 - 3y + 6 + y2 - 5y - 1 + (-4) + 2y2 - 2y
= 5y2 - 10y + 1
3. 2x2y - 3xy2 + x2y - 4x2y - 2xy2
= - x2y - 5xy2
4. x2 - y2 + 2x2 - 3xy + 4y2 + 3y2 - 5xy - x2
= 2x2 - 8xy + 6y2

Answer:
Answer: B, 6/11
Step-by-step explanation:
<em>Well we know that 3+2+1=6+3=9.</em>
<em>So that means we will add the 2 brown crayons to the denominator.</em>
<em>The denominator before we added 2 to it, it was 9 as a common denominator. If we want to get the common numerator we are going to have to add the top and that will become 9 then you will have to subtract that by 3</em>
<em>6/11 is also the smallest number that you can get.</em>
<em>You can turn the fraction into a decimal and have it that way to make it easier.</em>
<em>When you turn a fraction into a decimal the number is always the same but with comparing numbers it is a lot easier to do than comparing fractions</em>
