<h3>What are algebraic expressions?</h3>

Algebraic expressions are expressions that comprise of variables, terms, coefficients and constants.

They are also made up of certain mathematical operations.

Given the expression;

(3 + 16.4a) − (9 + 5.7a)

expand the bracket

3 + 16. 4a - 9 - 5. 7a

collect like terms

16. 4a - 5. 7a - 9 + 3

add or subtract like terms

10. 7a - 6

Thus, the expression in simplest form is 10.7a + (−6) . Option D
