Triangle? Like when you make the factor tree?
Answer:
6.34 (4 repeating)
Step-by-step explanation:
√36 = 6
6.34 (4 repeating) --> 6.3444
6.34 (34 repeating) --> 6.3434
Equation is :
( x + 2 )² + ( y - 1 )² = r²
( - 4 + 2 )² + ( 1 - 1 )² = r²
4 = r², than we will plug in to a formula:
( x + 2 )² + ( y - 1 )² = 4
x² + 4 x + 4 + y² - 2 y +1 = 4
x² + y² + 4 x - 2 y + 1 = 0
