Part A: Solve the equation 5(x + 2) = 6x + 3x − 14, and show your work. (5 points)

Part B: Use this list of properties to justify each step of your math work. Justifications may be used more than once if needed. (5 points)

Addition Property of Equality

answer:

Part A: x = 6 Part B: answered in Explanation

Step-by-step explanation:

5(x +2) = 6x + 3x -14, first distribute on the left and combine like terms on the right.

5x + 10 = 9x - 14, subtract 5x from both sides and add 14 to both sides

24 = 4x, divide both sides by 4

6 = x

Part B: Distributive Property: distribute the 5 to the (x+2)

Combine Like Terms: any term with the same variable being combined ( 6x + 3x)

Subtraction, Addition, Division Properties of Equality: This simply means that what you do to one side you do to the other, as I indicated in the bold parts ( subtract 5x from both sides...)

answer:

Step 1: Combine like terms. ⇒ 10x - 18 = 6(x + 3) Step 2: Distributive Property. Step 3: Subtraction Property of Equality. Step 4: Combining like terms. Step 5: Addition Property of Equality. Step 6: Division Property of Equality.

Step-by-step explanation:

im not really smart ;-; im just gessing

y/x=18

step-by-step explanation:

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
