Pythagoras theorem.... The thing I hate the most..
In a traingle if you know two if its sides ( we say A and B ) you square them and get the third side C .
You didn't understand.
Let me explain.
We have a triangle, one side is 4cm other is 3cm how do you find the third side?
Yes, Pythagoras theorem.
That is a^2 + b^2 = c^2.
You square 4 and 3:
That will be 16 and 9 then you add them.
16+9= 25 find the root of 25 that is 5.
You get the third side as 5cm.
That's how you use Pythagoras theorem.
Answer:
9

Answer:
Step-by-step explanation:
x^2 - 17x - 60
(x - 20)(x + 3)
x^2 + 3x - 20x - 60
x^2 - 17x - 60
(x + 20) is not one of the factors
using F.O.I.L., it would have been
x^2 + 17x - 60

Answer:
2 feet per year
Step-by-step explanation:
First, we need to find the amount it grew:
13 - 3 = 10
So between 2005 and 2010 it grew 10 feet.
Now to find the yearly growth we need to divide the distance by time:
10 ÷ 5 = 2
So it grew 2 feet per year.
