Four students are simplifying the expression 5x(-3-7x).
Which student's work is correct?
O5x(-3-7x)
(5x)(-3) - 7x
-15x-7x
O 5x(-3-7x)
(5x)(-3) - (5x)(7x)
-15-35x
O5x(-3-7x)
-3 + 5x-7x
-3-2x
O5x(-3-7x)
(5x)(-3)+(5x)(-7x)
-15x-35x²

Answer 1

Multiplying the linear expressions, the correct sequence is given as follows:

• 5x(-3 -7x)

• (5x)(-3) + (5x)(-7x)

• -15x - 35x²

How are linear expressions multiplied?

They are multiplied applying the distributive property, in which all the terms are multiplied and the like terms are combined.

Hence:

5x(-3 -7x)

(5x)(-3) + (5x)(-7x)

-15x - 35x²

Hence the last option is correct.
