Answer:

not a right triangle

Step-by-step explanation:

We can use the Pythagorean theorem to see if it is a right triangle

a^2 + b^2 = c^2

15^2 + 12^2 = 21^2

225 + 144 = 441

369 = 441

This is not true so it is not a right triangle

Answer:

Step-by-step explanation:

A triangle is a right angled triangle if sum of squares of two sides is equal to the square of third side.

12²+15²=144+225=369

21²=441

so a²+b²≠c²

it is not a right angled triangle.

Yasmine bought 6 gallons of apple juice. After filling up 4 bottles of the same size with apple juice, she had 0.3 gallon of app
never [62]

1.425 gallons of apple juice are in one container

I got this because if she starts with 6 gallons and she’s left with 0.3 gallons, you would need to subtract 6 by 0.3 (6-0.3=5.7). So now you know how much is in 4 bottles. Now you need divide 5.7 by 4 to find out how much is in each container (which is 1.425).

What are the zeros of the function f (x) = (x-6)(2x+10)
bazaltina [42]

Let f(x)=0.

(x-6)(2x+10)=0

Using the zero-factor property, equate each factor to 0 and then solve for x.

\begin{gathered} x-6=0 \\ x=6 \\  \\ 2x+10=0 \\ 2x=-10 \\ x=-\frac{10}{2} \\ x=-5 \end{gathered}

Thus, the zeros of the given function are 6 and -5.

The zeros are the x-coordinate where the graph touches the x-axis.

Thus, the x-coordinates of where the graph touches the x-axis are -5, and 6.
