B
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
(x+5)^2
x^2+10x+25
(y+3)^2
y^2+6y+9
then it would be
x^2+10x+34+y^2+6y
subtract 34-36 since ur moving 36 to the left
where u get -2
so ur final equation would be x^2+y^2+10x+6y-2=0
Multiply both sides of the equation by (x+1), on the right hand side the denominator then goes away and on the left hand side you get (x+1)(x+1), foil that out then just solve for x
Area of one blade is
A=(1/2)b*h=(1/2)7*4=28/2=14
for four blades
14*4=56
