Answer:

4x² + 12xy + 9y²

Step-by-step explanation:

Assuming you require the expansion

(2x + 3y)²

= (2x + 3y)(2x + 3y)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(2x + 3y) + 3y(2x + 3y) ← distribute both parenthesis

= 4x² + 6xy + 6xy + 9y² ← collect like terms

= 4x² + 12xy + 9y²

Probability <br>1/4<br>3/4<br>1/2<br>5/8??​
Sindrei [870]

Answer:

1/2

Step-by-step explanation:

There are exactly 6 shaded regions; for every shaded region, there is also an unshaded region -- making this value 6 as well.

There are 12 possible outcomes, and 6 events

To determine probability, we divide the number of events by the number of possible outcomes, like this:

6/12=1/2\\1/2=.50\\

.50 = 50% or 1/2 chance.
