Answer:

The total cost of papering the 4 walls is **Rs. 1104**

**Step-by-step explanation:**

The given is:

- The length of a room is 3 times its breadth
- Its height is 4.6 m
- The total cost of carpeting the floor of a room at the rate of Rs. 60 per square meter is Rs. 4500

We need to find the total cost of papering the 4 walls at the rate of Rs. 6

Assume that the breadth of the room is x m

∵ The length of the room is 3 times its breadth

∵ The **breadth** of the room is **x** m

∴ The **length** of the room is **3 x **m

∵ The floor of the room is shaped a rectangle

- Area of the rectangle = length × breadth

∴ The **area of the floor** = (3 x) × (x) = **3 x²**

∵ The rate of the carpeting is Rs. 60 per square meter

- Multiply the area of the floor by 60 to find the total cost of carpeting

∴ The **total cost of carpeting** = 3 x²(60) = **180 x²**

∵ The **total cost of carpeting** the floor is Rs. **4500**

- Equate the two sides of total cost to find x

∴ **180 x² = 4500**

- Divide both sides by 180

∴ x² = 25

- Take √ for both sides

∴ **x = 5**

∴ The **breadth **of the room = **5 m**

∵ The length of the room is 3 x

∴ The **length **of the room = 3(5) = **15 m**

The four walls of the room has dimensions length × height , breadth × height , length × height , breadth × height ⇒ (each two opposite walls have same dimensions)

∵ The length = 15 m , breadth = 5 m , height = 4.6 m

∴ The area of the four walls = 2(15 × 4.6) + 2(5 × 4.6)

∴ The area of the four walls = 138 + 46

∴ The **area of the four walls** = **184 m²**

∵ The rate per meter square of papering is Rs. 6

- Multiply the area of the four walls by 6 to find the total cost

of papering

∴ The total cost of papering = 184 × 6

∴ The total **cost of papering** = Rs. **1104**

**The total cost of papering the 4 walls is Rs. 1104**

**Answer:**

5 x (7*x*²-3)

5 (7*x*²-3)

**Step-by-step explanation:**

Product means the result of multiplication.

Difference means the result of subtraction

Times indicates multiplication

square of means raised to the power of 2

The **product **__of 5 and the ____ difference__of

5 x (7x²- 3)

When you see "and" in between, this indicates the variables that are involved in the operation mentioned. Since it says the product of 5 and the difference of... This mean that 5 is multiplied to the quantity of the other operation used, which is the __difference of 7 times the square of x and 3. __

let that number be **x**

1.6 miles, because she started at -0.2, meaning you have to add another 0.2 to the total she hiked vertically. If she'd started 0.2 above sea level, you'd have to subtract 0.2 from 1.4.

Lets say the number we are solving for is a

Divide 7 on both sides

Divide 7 on both sides

7 **times** approximately 4.4 equals approximately 31 .

To find the number that, when **multiplied** by 7, equals 31, we need to solve the equation :

7 * x = 31

Here, x represents the unknown** number** we are trying to find .

To isolate x, we divide both sides of the equation by 7 :

( 7x ) / 7 = 31 / 7

Simplifying, we have :

x = 31 / 7

Calculating the** division**, we find :

x ≈ 4.4285714

x = 4.4

7 * 4.4 = 31

Therefore, 7 times approximately 4.4 equals approximately 31 .
