AOC = 90⁰

3x + 46 + 14 = 90⁰

3x = 90⁰ - 60⁰

3x = 30⁰

x = 10⁰

Bruno solved the following equation: 4x + one half(10x − 4) = 6 Step Work Justification 1 4x + 5x − 2 = 6 2 9x − 2 = 6 3 9x = 8
beks73 [17]

Answer:

Statement                                   Reason

1. 4x+5x-2=6                 1. Distributive Property

2. 9x-2=6                        2. Combine like terms

3. 9x=8                              3. Addition Property of Equality

4. x=\dfrac{8}{9}                               4. Division Property of Equality

Step-by-step explanation:

The given equation is

4x+\dfrac{1}{2}(10x-4)=6

Using distributive property, we get

4x+\dfrac{1}{2}(10x)+\dfrac{1}{2}(-4)=6

4x+5x-2=6

9x-2=6         (Combine like terms)

Using Addition Property of Equality, add 2 on both sides.

9x=6+2

9x=8

Using Division Property of Equality, divide both sides by 9.

x=\dfrac{8}{9}

Which expression is a difference of squares with a factor of 5x − 8?
Olegator [25]

Answer:

25x^2-64

Step-by-step explanation:

Remember that the formula for the difference of squares is a^2-b^2=(a+b)(a-b). The formula implies that if (5x - 8) is a factor, then (5x + 8) is the other factor. We can use our formula to find which one is our difference of squares:

(5x-8)(5x+8)=(5x)^2-8^2

(5x-8)(5x+8)=5^2x^2-64

(5x-8)(5x+8)=25x^2-64

We can conclude that the correct answer is 25x^2-64.
