Answer:
take the common between dy and y
do similarly also with x .and make a equation
Answer:
Hypotenuse length is (√2)x if the leg lengths are x and x respectively.
Step-by-step explanation:
This is an isosceles right triangle. The two acute angles are 45 degrees each and the leg lengths can be represented by x. Applying the Pythagorean Theorem, we get x^2 + x^2 = h^2 (where h is the length of the hypotenuse), or
2x^2 = h^2.
Solve this for h. Taking the square root of both sides of this equation, we get:
(√2)x = h
Conclusion: if the two legs of this equilateral right triangle are x and x, respectively, the length of the hypotenuse is h = √2x.

Step-by-step explanation:
Answer:
f(- 1) = 3
Step-by-step explanation:
To evaluate f(- 1), substitute x = - 1 into f(x) , that is
f(- 1) = (- 1)² - 2(- 1) = 1 + 2 = 3
