There is a 1/3 chance that a red marble would be chosen.

To find out you put add up the marbles, so they will make 12 marbles.

Since there are 4 red you put 4/12.

4/12 simplified is 1/3.

So the chance of a red marble being picked is 1/3.

Can someone help me in number 3 please
Sholpan [36]

Area of rectangle is the multiplication between the sides.


The first rectangle:


A = (2x + 5) . (3x - 2)

A = 2x . 3x - 2 . 2x + 5 . 3x - 2 . 5

A = 6x² - 4x + 15x - 10

A = 6x² + 11x - 10


The second rectangle:


A = (5y + 5) . (2y - 3)

A = 5y . 2y - 3 . 5y + 5 . 2y - 3 . 5

A = 10y² - 15y + 10y - 15

A = 10y² - 5y - 15
