Answer: Choice B
=========================================================
Explanation:
We'll be using the converse of the pythagorean theorem.
If we had a triangle with sides a,b,c and 
was true, then we have a right triangle. Note: c is always the longest side
For the first answer choice we have: a = 5, b = 8, c = 12
Then,
which is false. This shows that we do not have a right triangle with sides 5,8,12. This rules out choice A. Choice C is a similar story.
Choice B on the other hand works because
We have a true statement at the end, which confirms <u>choice B</u> is a right triangle.
Answer:
(n - 8n)(m+8n)
Step-by-step explanation:
x² - y² = (x - y)(x + y)
In this situation, the "x" = m and the "y" = 8n
So,
m² - 64n² = (n - 8n)(m+8n)
Answer:
y = kx
Step-by-step explanation:
In proportional relationships, the value of one variable increases as the other increases or decreases as the other decreases. It is denoted mathematically as y ∝ x where x and y are the variables. It follows that
y = kx where k is the proportionality constant.
So in the relationship where x represents the number of adults, and y represents the number of students,
y ∝ x and y = kx
y = kx is the required equation
Answer:
The answer is 25g^R4
Step-by-step explanation:
When you solve the equation, it becomes 25g^R4, it doesn't result in a whole number.
Answer:
3750
Step-by-step explanation:
each number is being multiplied by five
6*5=30
30*5=150
150*5=750
750*5= 3750
