Question

Which shows two expressions that are equivalent to (-7) (- 15) (-5)?

(-7) (-75) and (- 1) (525)
(-1) (525) and (35) (- 15)
(35) (-15) and (115) (-5)
(-1) (525) and (115) (-5)

Answer 1

Two expressions that are equivalent to (-7)(-15)(-5) are (-7)(-75) and (-1)(525)(-1)(525). When multiplying two negative numbers, the result is positive.

Step-by-step explanation:

Two expressions that are equivalent to (-7)(-15)(-5) are:

1. (-7)(-75)
2. (-1)(525)(-1)(525)
3. (35)(-15)
4. (115)(-5)

When multiplying two negative numbers, the result is positive. Therefore, (-7)(-15)(-5) can be simplified as follows:

1. (-7)(-15)(-5) = (-7)(-1)(-5)(15) = (-7)(75)(-5) = (-7)(-75)
2. (-7)(-15)(-5) = (-1)(525)(-5) = (-1)(525)(-1)(525)
3. (-7)(-15)(-5) = (35)(-15)
4. (-7)(-15)(5) = (115)(-5)
