Answer 2

1.) 20 * a * 5 = 100a
2.) (7 - c) * 8 = 7 * 8 - 8c
56 - 8c

Answer 3

To simplify the given expressions:

1. 20 • а • 5: We can simplify this expression by multiplying the numbers together. Assuming "a" is a variable, we can rewrite the expression as follows:

20 • а • 5 = 100 • а

So, the simplified expression is 100a.

2. (7 – с)8: To simplify this expression, we need to perform the subtraction first, and then multiply the result by 8. Assuming "c" is a variable, we can simplify the expression as follows:

(7 – с)8 = (7 – c) * 8

So, the simplified expression is (7 – c) * 8.
