Answer: D.
The open circle means it could be equal to the starting number
The Pythagorean theorem tells you
... a² + b² = c²
so
... a² = c² - b² = 16² - 9² = 256-81 = 175
... a = √175 = √(25·7)
... a = 5√7
Answer:
infinite solutions
x is all real numbers
Step-by-step explanation:
2x+1+x=3(x-2)+7
Distribute
2x+1 +x = 3x -6+7
Combine like terms
3x+1 = 3x+1
Subtract 3x from each side
3x-3x+1 = 3x-3x+1
1=1
This is always true, so it doesn't matter what value we put in for x
X is all real numbers
