Factoring
Completing the Square: -b/(2a)

Step-by-step explanation:

Step 1: Define

x² - 8x + 15 = 0

Step 2: Solve for x

[Subtraction Property of Equality] Subtract 15 on both sides: x² - 8x = -15
Complete the Square [Addition Property of Equality]: x² - 8x + 16 = -15 + 16
[Complete the Square] Simplify: (x - 4)² = 1
[Equality Property] Square root both sides: x - 4 = ±1
[Addition Property of Equality] Add 4 on both sides: x = 4 ± 1
Evaluate: x = 3, 5

An employee of a store's gift wrapping center is wrapping 8 gifts

Hitman42 [59]

The area A of a rectangle is A = bh, where b is the base of the rectangle and h is the height. The area of each rectangle with side lengths 1.5 ft and 2 ft is 1.5 × 2 = 3ft2. Since there are two rectangles with these dimensions, the combined area is 2 × 3 = 6 ft2. The area of each rectangle with side lengths 1.5 ft and 2.5 ft is 1.5 × 2.5 = 3.75 ft2. The area of each rectangle with side lengths 2 ft and 2.5 ft is 2 × 2.5 = 5 ft2. Since there are two rectangles of each type, the combined area is 2 × 3.75 + 2 × 5 =17.5 ft2. So, the total surface area of the box is 6 ft2+ 17.5 ft2 = 23.5 ft2

The employee needs to wrap 8 boxes, each with a surface area of 23.5 ft2. So, the combined surface area needing to be wrapped is 8 × 23.5 = 188 ft2. Since there is only 160 square feet of wrapping paper left, the employee will not be able to wrap all of the gifts
