I don’t know if you meant b^2 and c^2 or b x 2 and c x 2 so I’ll do both.
If it’s meant to be multiplied by 2, then you do 9^2 + (40)2 =c2
81 + 80 = c2
161 = c2
/2
80.5 = c
However I do doubt it’s that. This means it’s likely meant to be squared instead. In which case, use the following answer.
9^2 + 40^2 =c^2
1681 = c^2
Then square root both sides to get just c (which i assume is what you’re trying to find?)
Square root of 1681 = 41
So your answer would be 41.

Step-by-step explanation:
The augmented matrix is the 3×4 matrix of the coefficients in the standard-form equations.
![\left[\begin{array}{ccc|c}5&-4&-6&-3\\1&-3&1&-1\\-3&-6&7&1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Cc%7D5%26-4%26-6%26-3%5C%5C1%26-3%261%26-1%5C%5C-3%26-6%267%261%5Cend%7Barray%7D%5Cright%5D)
12/9 reduced in simplest form would be 4/3 or 1 1/3. You can pick which one you want to do :). They are both the same thing just one is an improper fraction and the other is a mixed number. I got this answer by dividing both the top and the bottom (The denominator and the numerator) by three.
Answer:
5^3
Step-by-step explanation:
125= 5*25
25=5*5
5 is a prime number and there are 3 of them so the answer in index notation will be 5^3
The expressions in which the numbers, or variables, or both, are connected by operational signs (+, - etc.) are called algebraic expressions. For example 5, 4x, a+b, x−y.
