Explanation

To find the time required to paint 3000m²:

First, find the painter's rate:

250m² / 8 hours = 31.25m²/hour

Now, divide the total area by the rate:

3000m² / 31.25m²/hour ≈ 96 hours

Explanation

The given expression is:

a³ + 3ab(a + b) + b³

Factor the expression:

(a + b)(a² - ab + b²) + 3ab(a + b)

Combine like terms:

(a + b)(a² - ab + b² + 3ab)

Simplify:

(a + b)(a² + 2ab + b²)

Recognize the perfect cube:

(a + b)³

Explanation

Given:

x + (1/x) = 8

Cube both sides:

(x + (1/x))³ = 8³

Expand the left side:

x³ + 3x²(1/x) + 3x(1/x)² + (1/x)³ = 512

Simplify:

x³ + 3x + 3(1/x) + (1/x)³ = 512

Rearrange:

x³ + (1/x)³ + 3(x + (1/x)) = 512

Substitute x + (1/x) = 8:

x³ + (1/x)³ + 3(8) = 512

x³ + (1/x)³ + 24 = 512

Subtract 24 from both sides:

x³ + (1/x)³ = 488

Explanation

A metaphor directly compares two unrelated things without using "like" or "as" — here, life is directly called a box of chocolates.

It implies that life is full of surprises, just like assorted chocolates in a box.

Explanation

To round off 87.321756 to 5 significant figures, we look at the 6th significant figure, which is 6.

Since it's greater than 5, we round up the 5th significant figure.

87.321756 becomes 87.322
