Answer:
x = 4
y = 2√2
Step-by-step explanation:
This triangle can be recognized as a 45 - 45 - 90, right isosceles triangle. The hypotenuse in a right isosceles triangle is √2 times a leg. We can say:
x = √2 * 2√2
x = 4
Since the triangle is isosceles, we can say the legs are equal, therefore:
y = 2√2
Answer:

hope this helps :)
The difference is the subtraction between the numbers;
15-5y
Factor out 5 because it's a common factor;
5(3-y)
Answer:
68.6 m/s
Step-by-step explanation:
The instantaneous velocity is ...
s'(t) = 2(4.9)t = 9.8t
Then ...
s'(7) = 9.8(7) = 68.6 . . . . meters per second
