Answer:
60
Step-by-step explanation:
Pythagorean Theorem; a² + b² = c²
a = 11
b = ?
c = 61
You can solve to get 60
10x+4
3x+4+7x
=10x+4
Add the numbers with the same variable
Answer:

Step-by-step explanation:
Given
5x³ + 40
← factor out 5 from each term
= 5(x³ + 8
)
x³ + 8
← is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b²)
x³ + 8![y^{6}](https://tex.z-dn.net/?f=y%5E%7B6%7D)
= x³ + (2y²)³ → a = x and b = 2y²
= (x + 2y²)(x² - 2xy² + 4
)
Hence
5x³ + 40![y^{6}](https://tex.z-dn.net/?f=y%5E%7B6%7D)
= 5(x + 2y²)(x² - 2xy² + 4
) ← in factored form
