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

  • 5x(-3 -7x)
  • (5x)(-3) + (5x)(-7x)
  • -15x - 35x²

<h3>How are linear expressions multiplied?</h3>

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.

x=4/(-4)

x=-1

y=x-3

y=-1-3

y=-4

sergejj [24]

Answer:

The total money raised by two Friends in fundraiser is $ ( 17 d + 15).

Step-by-step explanation:

Money raised by one friend  = $ (9 d + 10)

Money raised by other friend  =  $ (8 d + 5)

Now, Total Money raised together

= Money Raised by friend 1 + Money raised by friend  2

= $ (9 d + 10)   +   $ (8 d + 5)

= ( 9d + 8d) + ( 10 + 5)

= 17 d  + 15

or, Total Money  = ( 17 d  + 15 )

Hence, the total money raised by two Friends in fundraiser is $ ( 17 d + 15).
