Question

Simplify the expression: – 2f + 5f – f – 8f – 10f

a) -2f
b) -4f
c) -16f
d) -20f

Answer 1

The expression – 2f + 5f – f – 8f – 10f simplifies to – 16f. This is done by adding and subtracting the coefficients of 'f'. The correct answer is c) -16f.

Step-by-step explanation:

To simplify the expression: −2f + 5f − f − 8f − 10f, we need to combine like terms. This involves adding and subtracting the coefficients of the like terms, which in this case is the variable 'f'. Let's do this step-by-step:

• Combine −2f and 5f: (−2 + 5)f = 3f
• Subtract f from 3f: (3 − 1)f = 2f
• Subtract 8f from 2f: (2 − 8)f = −6f
• Finally, subtract 10f from −6f: (−6 − 10)f = −16f

The simplified expression is −16f.

The correct answer from the given options is c) -16f.
