What kind of a triangle has side lengths 4, 5, 6?
Reptile [31]

Answer:

hypotenuse

Step-by-step explanation:

It states that a2 + b2 = c2 for the sides of any right triangle (c is the hypotenuse, or longest side), AND it also states that if the three sides of a triangle obey this formula, they do form a right triangle. Since 6 is the longest sides, it would have to be the hypotenuse.

If g(x) = -2x+7, what is the new function defined by h(x) = g(2x^2 +1)
hammer [34]

Answer:

h(x) = - 4x² + 5

Step-by-step explanation:

To find h(x) = g(2x² + 1), substitute x = 2x² + 1 into g(x)

h(x) = - 2(2x² + 1) + 7

      = - 4x² - 2 + 7

      = - 4x² + 5

What is the product of − 3/11 and − 2/15? please explain.
emmainna [20.7K]

ANSWER

The product is

\frac{2}{55}

EXPLANATION

To find the product of

-  \frac{3}{11}

and

\frac{ - 2}{15}

means we should multiply the two fractions.

We multiply to obtain,

-  \frac{3}{11}  \times  -  \frac{2}{15}

=  -  \frac{3}{11}  \times  -  \frac{2}{3 \times 5}

Cancel the common factors:

=  -  \frac{1}{11}  \times  -  \frac{2}{5}

Now, multiply the numerators separately and the denominators too separately.

=  \frac{ - 1 \times  - 2}{11 \times 5}

This simplifies to,

= \frac{2}{55}
