Answer: The product is: 9r-28

Step-by-step explanation:

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

5r x 3r = 15r

5r x -4 = -20r

2 x 3r = 6r

2 x -4 = -8

Put it all together:

15r-20+6r-8

Then simplify:

9r-28

A bag contains green marbles and blue marbles,

dexar [7]

There are 13 green marbles in the bag.

Step-by-step explanation:

Total marbles = 18

Let,

Green marbles = x

Blue marbles = y

According to given statement;

The number of green marbles is 2 less than 3 times the number of blue marbles.

x = 3y-2 Eqn 1

x+y=18 Eqn 2

Putting value of x from Eqn 1 in Eqn 2;

$(3y-2)+y=18\\3y-2+y=18\\4y=18+2\\4y=20$

Dividing both sides by 4

$\frac{4y}{4}=\frac{20}{4}\\y=5$

Putting y=5 in Eqn 1

$x=3(5)-2\\x=15-2\\x=13$

There are 13 green marbles in the bag.
