Question

A^2+2b/a-a при a=0.2 b=4

Answer 1

0,2*2=0.04

2*4/0.2=40

40-0.2=39.8

39.8+0.04=39.804

Answer 2

А^2+2b/a-a

0,2^2+8/0,2-0,2

0,4+40-0,2=40,2

Answer 3

To evaluate the expression A^2 + 2b/a - a with the given values a = 0.2 and b = 4, follow these steps:

1. Substitute the values of a and b into the expression.
2. Perform the calculations.

Let's go through the steps:

1. Substitute the values: A^2 + 2b/a - a = A^2 + 2(4)/0.2 - 0.2

2. Perform the calculations: A^2 + 8/0.2 - 0.2 = A^2 + 40 - 0.2

Now, I noticed that the variable 'A' is not assigned any specific value, so I cannot provide an exact numerical result without knowing the value of 'A'. However, I can simplify the expression if that helps. Here's the simplified expression:

A^2 + 39.8

If you have a specific value for 'A', you can plug it in to find the numerical result. For example, if A = 3:

3^2 + 39.8 = 9 + 39.8 = 48.8

Remember, this result is only valid if you have a specific value for 'A'. Otherwise, the expression remains in terms of 'A'.
