If a, b and c are the lengths of a right triangle and c is the longest side, then:
We have a = 18cm, b = 24cm and c = 30cm. Substitute and check:
<h3>Answer: It's the right triangle.</h3>
Answer:
5x-8y
Step-by-step explanation:
4x-9y+x+y
=4x+-9y+x+y
=4x+-9y+x+y
=(4x+x)+(-9y+y)
=5x+-8y
=5x-8y
The constants are 2, -10, and 5
the variables are x and y
To find the mean, you add up the numbers and divide by
how many numbers there are.
So if the mean of 'A' and 'B' is 40, then A + B = 80 .
And if the mean of 'B' and 'C' is 35 then B + C = 70.
==========================================
You said that (A + B) + C = 100 .
From something else that you said, I noticed that A + B = 80 .
So I can write (80) + C = 100
Subtract 80 from each side: C = 20
==========================================
I also noticed, from what you said, that B + C = 70 .
So I can write B + 20 = 70
Subtract 20 from each side: B = 50
==========================================
Now I know that C = 20 and B = 50.
Finally, you said that A + B + C = 100 ,
So I can write A + 50 + 20 = 100
Combine like terms on the left: A + 70 = 100
Subtract 70 from each side: A = 30
==========================================
<em> A = 30</em>
<em> B = 50</em>
<em> C = 20</em>
