Answer:
25x^2 - 4
Step-by-step explanation:
and x times an x is x^2 so
25x^2 - 4
The answer to your question would be -8
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
