If the squares of the shorter sides added together are:

Equal to the square of the longest side - the triangle is right angled
Less than the square of the longest side - the triangle is obtuse angled
More than the square of the longest side - the triangle is acute angled 

This example would be right, which comes from the Pythagoras theorem

I think that it's an obtuse triangle.

Answer:

0.015 miles

Step-by-step explanation:

1mile = 4min \\ 1mile = 240sec \\ 0.609km = 240sec \\  \frac{0.609}{24}  =  \frac{240}{24}  \\ 10sec = 0.025km \\ 10sec = 0.015miles

Answer:

Its 9.0 units

Step-by-step explanation:

For the side mostly to the left, its gonna be 3 units, since we can easlily count it

Now, for the diagonals, we have to use the formula for the area of a triangle, which is (l * w) / 2 = a.

For the bottom side, its 3 along the x axis and 1 along the y axis. 3 * 1 is 3, now divide that by 2 and you got 1.5

Now, for the right side, its 5 on the y, 1 on the x. Multiply 1 by 5, you got 5. Now divide that by 2 and you have 2.5

Finally, for the top side, its 4 on the x, and 1 on the y. 4 * 1 is 4, divided by 2 and its 2.

Alright, now we have to add 'em all together. 3 + 1.5 + 2.5 + 2 is 9 units

Theres your answer :)

Match each equation to its factorized version and solution.
bagirrra123 [75]

Answer:

24x -{6x}^{2}  = 0 \: matches \: with \: 6x(4 - x) \: and \: the \: solution \: x = 0 \ \: or \:  \: x = 4

2 {x}^{2}  + 6x = 0 \: matches \: with \: 2x(x + 3) = 0 \: and \: the \: solution \: x = 0 \: or \: x =  - 3

4x -  {x}^{2}  = 0 \: matches \: with \: x(4 - x) = 0 \: and \: the \: solution \: x = 0 \: or \: x = 4

14x -  {7x}^{2}  = 0 \: matches \: with \: 7x(2 - x) = 0 \: and \: the \: solution \: x = 0 \: or \: x = 2
