Which expression is equal to 45 x 4-734-27

45 = 4 0

9(5x - 3) option (c)

Step-by-step explanation:

The question isn't clear as well as incomplete without the options. Since there are no options let's determine the answer of the following mathematical expression:

45x - 27

a) 9(3x - 5)

b) 3(12x + 7)

c) 9(5x - 3)

d) 5(7x + 30)

To determine which option is equivalent to 45x - 27, we would check each option by expanding the bracket. Apply BODMAS (stands for Bracket, Of, Division, Multiplication, Addition and Subtraction) after the expansion. That is multiply before you add or subtract.

a) 9(3x - 5) = 9×3x - 5×9

= 27x - 45

b) 3(12x + 7) = 3×12x + 3×7

= 36x + 21

c) 9(5x - 3) = 9×5x - 9×3

= 45x - 27

d) 5(7x + 30) = 5×7x + 30×5

= 35x + 150

From the expansion, only option C is equal to the given expression: 45x - 27
