Answer:

8 grams

Step-by-step explanation:

The balance is in equilibrium, so the weights of the two sides are equal.

Let the weight of a square be s.

Left side: 2s + 4

Right side: s + 3(4) = s + 12

The weights are equal, so we set the two expressions equal.

2s + 4 = s + 12

s = 8

Answer: The weight of a square is 8 grams.

Question 2: The first step was the combine the like terms; in this example he is subtracting the 3x on both sides of the =.

Answer: x=14

only #2

Step-by-step explanation:

Step 1: Subtract 3x from both sides.

2x+6−3x=3x−8−3x

−x+6=−8

Step 2: Subtract 6 from both sides.

−x+6−6=−8−6

−x=−14

Step 3: Divide both sides by -1.

-x/-1=-14/-1

Add like terms from both trinomials:

4x^{2} + -2x^{2} = 2x^{2}
2x + -5x = -3x
-1 + 3 = 2

Combine these terms to get a new trinomial as your answer:

2x^{2} - 3x + 2


13. 
Subtract like terms from both trinomials (note that subtracting a negative is the same as adding it as a positive):

3x^{2} - 5x^{2} = -2x^{2}
-8x - -11x = -8x + 11x = 3x
-1 - -1 = -1 + 1 = 0

0 can be left out of the answer.

Combine these terms to get a binomial as your answer:

-2x^{2} + 3x
