Answer:

2 1/2

Step-by-step explanation:

If you do the step by step calculation:

Step 1: Simplify both sides of the equation.

2(12+2x+15+2x)=74

(2)(12)+(2)(2x)+(2)(15)+(2)(2x)=74(Distribute)

24+4x+30+4x=74

(4x+4x)+(24+30)=74(Combine Like Terms)

8x+54=74

8x+54=74

Step 2: Subtract 54 from both sides.

8x+54−54=74−54

8x=20

Step 3: Divide both sides by 8.

8x divide by 8 and that is 20 divided by 8

leaves you with the answer 5/2.

If you then turn the improper fraction into a mixed fraction you get 2 and one half.

Answer= 2 1/2 or "a" <u>DEPENDS ON WHAT QUIZ YOU HAVE</u>

Answer:

n^{3} + 15n^{2} + 56n

Step-by-step explanation:

First FOIL  (n + 7)(n + 8) and then distribute n

(n + 7)(n + 8) = n^{2} +15n + 56

 n (n^{2} +15n + 56)

= n^{3} + 15n^{2} + 56n

The container that holds the water for the football team is
Rom4ik [11]

Answer:

30 Gallons

Step-by-step explanation:

Okay so you need to start by making an equation for yourself. Since the container starts at 1/10 of the total, you want to start by saying 1/10x. Then you add 12 gallons of water to make it half full. So 1/10x + 12 = 1/2x where x is the total amount that can fit in the container.

1/10x + 12 = 1/2x (Move your x's to the same side.)

12 = 1/2x - 1/10x (Find a common denominator.)

12 = 5/10x - 1/10x (Simplify/)

12 = 4/10x (Multiply both sides by 10; your demoninator)

120 = 4x (Divide)

x = 30

Your container holds 30 gallons.
