Answer:
x = (64 + 5) ÷ 3
Step-by-step explanation:
3x - 5 = 64
Add 5 to both sides: 3x = 64 + 5 = 69
Divide both sides by 3: x = 69 ÷ 3 = 23
So the answer is x = (64 + 5) ÷ 3
Note: If we didn't add the parentheses then using the order of operation x = 64 + 5 ÷ 3 would be x = 64 + = 65
The area of the rectangular patio to be painted is: B. A = (x + 20)(x + 10) - 12.
<h3>What is a Rectangle?</h3>A rectangle, by definition, is a quadrilateral with two pairs of opposite that have the equal lengths. All four angles of a rectangle are right angles (90 degrees).
<h3>What is the Area of a Rectangle?</h3>The area of a rectangle = (length of rectangle)(width of rectangle).
Given the following parameters for the patio and the bench:
Area to be painted = area of rectangular patio - area of rectangular bench
Area of rectangular patio = (x + 20)(x + 10)
Area of rectangular bench = (6)(2) = 12
Area to be painted = (x + 20)(x + 10) - 12
The answer is: B. A = (x + 20)(x + 10) - 12.
