Question

26 а + 421 + 74 а - 241,если а=39

Answer 1

26 а + 421 + 74 а - 241=100а+180
при а=39,то 100•39+180=4080

Answer 2

To evaluate the expression 26а + 421 + 74а - 241 when а = 39, we need to substitute the value of а into the expression and perform the arithmetic calculations.

Let's do that step by step:

1. Substitute the value of а: 26 * 39 + 421 + 74 * 39 - 241

2. Perform the multiplications first: 1014 + 421 + 2886 - 241

3. Perform the additions and subtractions from left to right: (1014 + 421) = 1435 (1435 + 2886) = 4321 (4321 - 241) = 4078

So, the result of the expression 26а + 421 + 74а - 241, when а = 39, is 4078.
