Question

# A bricklayer uses the formula to estimate the number of bricks, n , needed to build a wall that is l feet long and h feet high. Which of the following correctly expresses l in terms of n and h ?

Hint:

**Hint:**

- An expression is a combination of symbols used in algebra, containing one or more numbers, variables, and arithmetic operations

## The correct answer is:

### Explanation:

- We have given the formula for calculating the number of bricks.
- We have expressed l in terms of n and h.
- We will use simple mathematical operations to express the given formula for l

Step 1 of 1:

The given formula for the number of bricks is

Now multiply both hand side with .

So,

Therefore,

So, option (c) is correct.

Final answer:

Hence, l can be expressed in terms of n and h as .
