1) The expressions are not equivalent. When you expand and multiply 2(x + 3) it becomes 2x + 6. This is not equal to 3x + 5
2) They are equivalent. Again, expand and multiply the second expression. 2(3n + 4) becomes 6n + 8. This makes both sides equal.
3) They are equivalent. In the parentheses, you are adding 3 y's and a 2. This gives you 3y + 2. Now add the additional 3y that follows the closed parentheses. You'll have 6y + 2. Now both sides are equivalent.
okay so first you do 6 times 2 you got 12 so maybe 2.5 times 6 and that is 15 so now you multiply 4.5 times 2.5 and i got 11.25. So 11.25 pounds of chicken is needed.
The answer is 91. 260 people were surveyed, and 35 percent said yes. 35 percent of 165 is 91.
