Quadrilateral WXYZ is a rectangle. If angle ZYW = 2x-7 and angle WYX = 2x+5, find the measure of angle ZYW.

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%

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

umm you say your want to . but you do know that this is the mathematics.
