Question

7,35а - а², при а = 6,35​

Answer 1

Вынесу а за скобки:

7,35а - а^2 = а(7,35 - а)

подставляю 6,35 вместо а:

6,35 (7,35-6,35) = 6,35 * 1 = 6,35

Answer 2

To evaluate the expression 7.35a - a² when a = 6.35, we substitute the value of a into the expression and perform the calculation.

Let's substitute a = 6.35 into the expression:

7.35(6.35) - (6.35)²

Now we can calculate:

7.35(6.35) = 46.5225 (6.35)² = 40.3225

Substituting the values back into the expression:

46.5225 - 40.3225 = 6.2

Therefore, when a = 6.35, the value of the expression 7.35a - a² is 6.2.
