stealth61 [152]3 years ago
3 0

The answers are:

1. A) 3

2. A) 24.5

3. C) 180

In order to find this, we need to multiply the first two together.

1.

15% * 20

.15 * 20

2.

35% * 70

.35 * 70

The last problem is a little different. Since the decimal comes second, you need to divide instead of multiply.

90/50%

90/.50

Answer:

14x + 23

Step-by-step explanation:

The lengths of three sides of a triangle are 5x + 9 feet, 2x + 14 feet, and 7x feet.

The perimeter of a triangle: the sum of all of its sides.

5x + 9 + 2x + 14 + 7x

14x + 23

It's the expression of the perimeter of the triangle. Once you will be asked to find x, you'll probably be given the exact perimeter of the triangle.
