Answer 2

Option D.

Explanation:

The given expression is (5r + 2)(3r minus 4)

Convert this expression into an algebraic expression.

(5r + 2)(3r - 4)

By distribution law,

= 5r(3r - 4) + 2(3r - 4)

= 15r² - 20r + 6r - 8

= 15r² - 14r - 8

Now convert the algebraic expression into the language form.

15r squared minus 14r minus 8

Therefore, option D is the answer.
