Answer:
B. 3, 3, 2
Step-by-step explanation:
The triangle inequality requires the sum of the lengths of the two shortest sides exceed the length of the longest side. That is the case only for the lengths of selection B:
2 + 3 > 3
a = √(13² - 12²) units
<h3>
Further explanation</h3>
<u>Given:</u>
- A right triangle has a hypotenuse length of 13 units.
- One leg has a length of 12 units
<u>Question:</u>
Which equation can be used to determine the length of the other leg?
<u>The Process:</u>
We will solve a problem regarding right triangles. In the process, there is a relationship between the Pythagorean Theorem with Exponent and Square Root.
Let us find out the equation to determine the length of the other leg. Let the length of the leg as "a".
The Phytagorean Theorem:
Subtract by 12² on both sides.
To take the square root on both sides.
So here's the equation that can be used to determine the length of the other leg: 
- - - - - - - - - -
Notes
If we continue working on the above, the results will be as follows:
Hence the length of the other leg equal to a = 5 cm.
Of course, we agree with the use of the right intuition, which is to remember Pythagorean Triples, i.e., 
This method is very convenient when working on multiple-choice tests in a limited amount of time.

The weight of one foot of the steel pipe is 1.24 pounds or more accurately, 1.239905.... pounds.
This type of problem is solved using cross multiplication. You know the length (16.84 feet), and the weight (20.88 pounds), of the steel pipe. But what you do not know is the weight of one foot of the steel pipe. Since that is what we are solving for, the weight of one foot of the steel pipe will be our x variable.
This is how I set it up...
16.84 1
——— * ———
20.88 x
I came up with this equation. The length of the pipes I put in the numerator (top), and the weight I put in the denominator (bottom). Since 16.84 feet of a steel pipe weighs 20.88 pounds, 1 foot of a steel pipe weighs x pounds. After you have the equation set up you then move on to cross multiplication.
Step 1: Multiply the top number of the first fraction by the bottom number of the second fraction.
16.84*x= 16.84x
Step 2: Multiply the bottom number of the first fraction by the top number of the second fraction.
20.88*1=20.88
Step 3: Set the answers from step 1 and step 2 equal to each other.
16.84x=20.88
Step 4: Divide 16.88 on both sides so x is by itself.
16.84x 20.88
——— = ———
16.84 16.84
And after you divide on each side you have your answer which should be x=1.24
Answer:
Its either 2(A+7=5) or 2(A+7) =5
Y=1 and x=7 because if you make the first equation into a x= equation, you can just substitute it for the second equation and solve it.
