Those lines on both sides of the number means "absolute value." Those lines tell us that the number is positive no matter what. So:

15 + |-3| - 4 → 15 + 3 - 4

Remember to follow PEMDAS when solving.

(15 + 3) - 4

18 - 4

14

Therefore, the answer is 14.

Best of Luck!

Answer: 14

Step-by-step explanation: The vertical bars around the -3 mean that we take the absolute value of that number which is the positive version of that number.

So the absolute value of -3 would be 3.

So we have 15 + (3) - 4 which simplifies to 18 - 4 or 14.

Notice that I used parentheses when first getting rid of the absolute value signs. I think that this method will help you avoid confusion when simplifying absolute values.

It's a good habit to get into for future problems.

Answer:

The area of the room is 432 square feet

Step-by-step explanation:

Let us use the ratio method to solve the question

∵ The scale drawing of the room is 1 inch: 3 feet

→ That means each 1 inch in the drawing represents 3 feet in real

∵ The drawing is 8 inches long by 6 inches wide

∴ The drawing length of the room = 8 inches

∴ The drawing width of the room = 6 inches

→ By using the ratio method

→  inches  :  feet

→  1            :  3

→  8           :  L

→  6           :  W

→ By using the cross multiplication

∵ 1 × L = 8 × 3

∴ L = 24

∴ The actual length of the room is 24 feet

∵ 1 × W = 6 × 3

∴ W = 18

∴ The actual width of the room is 18 feet

Use the formula of the area of the rectangle to find the area of the room

∵ Area of rectangle = length × width

∴ Area of the room = 24 × 18

∴ Area of the room = 432 feet²

∴ The area of the room is 432 square feet
