hello :
the area of the circle is : 40 cm²
40 = <span>πr²
r² = 40/(3.14 )
r² = 12.73 cm</span>
hector is 7 and a half
because 7 plus 7 is 14 buy 7.50 plus 7.50 is 15
Y= 2x+4, because when you plug in x and y you then solve for b and get 4. The 2x is the same because the slope stays the same on parallel lines.
Ok so its 50, -7.6, -7.64. then -157 divided by 20
