2(7+11)
This is the answer because you multiply everything in the parentheses by the number on the outside. So you multiply 2 x 7 and multiply 2 x 11. This will equal 14+22. Sorry if you don't understand too much but you should ask your teacher for help if you don't understand.

Answer:
To factor out the following expression you would you would need to remove the (a + 1) term out of the expression, which leads to :
(a+1) (b(a+1) - 5
Step-by-step explanation:
This is the final expression
Divide bags of sand by gallons of water:
14 /6 = 2.33
21/9 = 2.33
The ratio is the same, so this means for every gallon of water you need 2.33 bags of sand.
Convert the fractions into decimals and you will get 7/3 = 2.33
The answer for Part 1 is D) 7/3
For part 2, multiply the gallons of water by 2.33 to get the number of sand bags needed:
12 x 2.33 = 27.99, which rounds to 28.
The answer is C) 28 bags.
The answer should be 9,300
