A right triangle are 3 cm and 4 cm. What is the length of the hypotenuse?

1 answer:

3 0

Oh this is easy.

A² + B² = C²

A and B are the sides.

But it's a little known fact that if those sides are 3 and 4 units, the hypotenuse is 5. Make sure to keep that in mind, because this trick works for other problems that ask what the hypotenuse is if the sides are 6 and 8, then it's 10.

The answer is 5.

Factor 6x4 – 5x2 + 12x2 – 10 by grouping. What is the resulting expression?

lisov135 [29]

Your answer would be the last option, (6x² - 5)(x² + 2).
This is because when you expand it, you get:
6x² × x² = 6x⁴
6x² × 2 = 12x²
-5 × x² = -5x²
-5 × 2 = -10
Which are all the correct terms.

I hope this helps!

What are the zeros of the function below?

Ivan

When you want to find zeros of rational expression you need to find at which points numerator is equal to zero. In this case, we have the product of three expressions.
$x(x-1)(x+11)=0$
A product is equal to zero whenever one of the factors is equal to zero.
That means that zeros of our functions are:
1) $x=0$
2) $x-1=0$
$x=1$
3) $x+11=0$
$x=-11$
The final answer is a. Function has zeros at (0, 1, -11).
