Answer:
<em>12^2 + x^2 = 13^2</em>
Step-by-step explanation:
The student's error was that he didn't use the Pythagorean Theorem correctly
According to the Pythagorean Theorem, <em>a^2 + b^2 = c^2</em>, where c represents the hypotenuse
However, the student replaced <em>c</em> with <em>x</em>, which isn't the hypotenuse
The hypotenuse is 13, so <em>c</em> should be 13, not <em>x</em>
Answer:
The answer is 180.
Just multiply thirty and six.
Hope that helps!
Appears that you've overlooked the need to share the possible answer choices.
f(x)=x^2x-1 has a parabolic graph with vertex at (0,-1). This is also the location of the vertex. Because the coefficient of x^2 is positive, this graph opens up. Thus, the smallest possible y value here is -1. The range of this function is
[-1, infinity).
B I’m pretty sure it’s that
The answer is 36
Explanation because it’s 36
