Answer 2

Simplifying the Expression and Finding Its Value

To simplify the given expression and find its value when a=0.02, we can follow these steps:

1. Simplify the Expression: - The given expression is: 3.05a - 2.31a + 2.013 + 0.44a. - We can simplify this expression by combining like terms.

2. Substitute the Value of 'a': - After simplifying the expression, we can substitute the value of 'a' as 0.02 and calculate the result.

Simplified Expression

The simplified expression is: 3.05a - 2.31a + 2.013 + 0.44a.

Calculating the Value

Substituting a=0.02 into the simplified expression: 3.05(0.02) - 2.31(0.02) + 2.013 + 0.44(0.02).

Result

After performing the calculations, the value of the expression when a=0.02 is: 0.061 - 0.0462 + 2.013 + 0.0088 = 2.0366.

So, when a=0.02, the value of the expression 3.05a - 2.31a + 2.013 + 0.44a is 2.0366.
