= 1430a+545b

(1430•9)+(545•8) = 17230

Answer 2

To simplify the expression, let's substitute the given values of a = 9 and b = 8 into the expression:

624 × (a + b) - 79b + 806a

Replacing a with 9 and b with 8:

624 × (9 + 8) - 79(8) + 806(9)

Simplifying further:

624 × 17 - 79 × 8 + 806 × 9

Now we can calculate the expression:

10608 - 632 + 7254

The value of the expression is:

18422
