Simplify (2x-2y)(2y + 8)

=4xy−4y2+16x−16y

Step-by-step explanation:

(2x−2y)(2y+8)

=(2x+−2y)(2y+8)

=(2x)(2y)+(2x)(8)+(−2y)(2y)+(−2y)(8)

=4xy+16x−4y2−16y

=4xy−4y2+16x−16y

-4y^2+4xy+16x-16y

Step-by-step explanation: Hi there.

For this answer I will show you the FOIL method.

Form: (ax-by)(cy-d)

1. Multiply ax and cy

2x*2y=4xy

2. Multiply ax and d

2x*8=16x

3. Multiply by and cy

-2y*2y=-4y^2

4. Multiply by and d

-2y*8=-16y

Add all of them together and you get:

-4y^2+4xy+16x-16y

Have a nice day! :)

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
