Pythagoras theorem:
hypotenuse²=leg₁²+leg₂²
Data:
leg₁=4 u
leg₂=7 u
Therefore:
hypotenuse²=(4 u)²+(7 u)²
hypotenuse²=16 u²+49 u²
hypotenuse²=65 u²
hypotenuse=√(65 u²)≈8.06 u
Answer: the length of the hypotenuse is 8.06 u

Answer:
4 more pens
Step-by-step explanation:
Well, what do we know?
We know Sheila has:
6 pens
10 pencils
How many MORE pens does she need to make the number of pens <em>equal to </em>the number of pencils?
6 + x (x is the number of pens needed to EQUAL to 10)
6 + x = 10
x = 4
Sanity check:
6 + 4 = 10
Sheila needs 4 more pens to make the number of pens and pencils equivalent, or EQUAL TO each other.
Answer:
The answer is c = 25.13 a =50.27
The answer to this question is extremely simple. Think of it this way. When you have 2 apples and you eat one how many do you have left? Well we can use the Pythagorean theorem, a^2 + b^2 = c^2, so 2^2 -1^2 = ?. Well how do you find exponents?
Good. What is the Pythagorean theorem? The Pythagorean theorem consists of a formula a^2+b^2=c^2 which is used to figure out the value of (mostly) the hypotenuse in a right triangle. The a and b are the 2 "non-hypotenuse" sides of the triangle (Opposite and Adjacent). Very simple. So you would have one apple remaining.
