Question

What is the value of 4p − 2, when p = 8?

Answer 1

Put the value of p in the equation

Then,

4×(8)-2

32-2

30

Hence, the answer is 30.

Answer 2

30

Explanation:

Since p = 8, I write 8 instead of p:

4 × 8 - 2

And now I simplify using BODMAS (brackets, other, division, multiplication, addition, subtraction).

32 - 2

30

∴ 30
