"Three times" is represented as( 3X)
A number is unknown so it can be called X
And since it is equal to 9, the variable will be X.


3 X unknown (x) = 9 and a letter is known as a variable in mathematics so cherrio :)

Tell if the measures 6, 14, and 13 make a triangle that is acute, right, or obtuse.
ycow [4]

Right angle - c²=a²+b²

Obtuse angle - c²>a²+b²

Acute angle - c²<a²+b²

To see which ones go into a, b, and c, know that the largest number is the hypotenuse (variable c). The other two letters can be either a or b, so it doesn't matter which place they are put it because you will get the same answer.

right angle 14²=6²+13²

196=36+169

196≠205

-----------------------

obtuse angle 14²>6²+13²

196>36+169

196>205 is false

-----------------------

So since it is not a right angle or an obtuse angle, that means that it's a right angle because it's the only option left. Though we now know that's the answer, I will still put down the steps.

acute angle 14²<6²+13²

196<36+169

196<205 is true so it's an acute triangle.

Hope this helps, now you know the answer and how to do it. Stay safe and healthy and HAVE A BLESSED AND WONDERFUL DAY! :-)

It takes Andrew 720720720 seconds to take a shower. He spends an additional 420420420 seconds eating breakfast. How many minutes
Brilliant_brown [7]

Answer: 19 minutes

Step-by-step explanation:

Here is the complete question:

takes Andrew 720 seconds to take a shower. He spends an additional 420 seconds eating breakfast.

How many minutes does it take Andrew to take a shower and eat breakfast?

From the question, we are told that Andrew spends 720 seconds to take a shower and also spends an additional 420 seconds eating breakfast. The total time spent by Andrew will be:

= 720 seconds + 420 seconds

= 1140 seconds

We will then convert 1140 seconds to minutes. We should note that 60 seconds = 1 minute. Therefore,

1140 seconds = 1140/60

= 19 minutes

Andrew uses 19 minutes to take a shower and eat breakfast.
