So, we know that a^2 + b^2 = c^2. Right? That is called the Pythagorean Theorem.

In this case. We can say that 39 is a, 40 is b, and x is c.
NOTE: It doesn't really matter whether 39 is a or b. a & b are just the two legs of the right triangle.

So, if we say that 39 is a, 40 is b, and x is c. We can plug it into the Pythagorean Theorem.

39^2 + 40^2 = x^2

I'll let you take it from there.

What is 6 times less than 42

Oksana_A [137]

Hello!

Your answer would be 6

Than basically means switching the numbers

So basically if you were to multiply 6 x 6 (6 times less than)

You would get 36. Then subtract.

42 - 36 = 6, which is your answer.

I hope this helps!

If f(x) is a fifth degree polynomial, is it possible that it has exactly 5 complex roots?

Zolol [24]

No.

A fifth degree polynomial, having a graph that increases and starts from below x-axis.

Therefore, no matter what equation it is. The fifth degree polynomial will intercept x-axis AT LEAST one.

The fifth degree polynomial can have only at maximum, 4 complex roots.

<em>You can try drawing or seeing the graph of fifth-degree polynomial function. No matter what equations, they still intercept at least one x-value.</em>
