1. 20% decrease

2. 16% increase

Explaination:

Question 1.

30 inches to 24 inches is a decrease, because 24 is smaller than 30.

(30-24)/30 * 100%

= 6/30 * 100%

= 20%

Ans: 20% decrease


Question 2.

$126 to $150 is an increase, because 150 is larger than 126.

(150-126)/150 * 100%

= 24/150 * 100%

= 4/25 * 100%

= 16%

Ans: 16% increase

12. (07.06 LC) A library building is in the shape of a rectangle. Its floor has a length of (3x + 5) meters and a width of (5x −
Goshia [24]

ANSWER

15 {x}^{2} + 22x - 5

EXPLANATION

It was given that, the length of the rectangular building is

(3x + 5) \: meters

and the width of the is

(5x - 1) \: meters

The area of a rectangular building is calculated using the formula for finding the area of a rectangle.

A = l \times w

Since the dimensions are given in terms of x, the area is also a function of x,

A(x) = (3x +5 )(5x - 1)

We expand to get,

A(x) = 3x(5x - 1) + 5(5x - 1)

A(x) = 15 {x}^{2}  - 3x + 25x - 5

A(x) = 15 {x}^{2} + 22x - 5

meters square
