FIRST PROBLEM AS GENIUS!!!
The 45-45-90 triangle theorem states that each leg equals x, and the hypotenuse equals

. Using this, we can find that the height is 10. Take the average of the lengths to get l = 27.
The area = 270.
Answer:
2b + 4 = 22
b= 9, the cost of each game is $9
Step-by-step explanation:
Area of square = a^2 = 4^2 = 4 x 4 = 16
answer
16
W- (3,4)
Z- (-1,1)
X-(-1,-3)
Y-(-4,1)
Answer:
