Question

Write the following sentence using mathematical symbols:

The product of 4 and x is less than or equal to -20.

Answer 1

We will write each part of this sentence:

The product of 4 and x: This means 4 and x are getting multiplied, so 4x

Less than or equal: This is what we mean with this symbol
`\leq`

So we know that
`4x \leq -20`

Answer 2

`4x\leq -20`

Explanation:

Product refers to multiplication, hence the 4x.
