Answer:
7.74 cm^2
Step-by-step explanation:
The length of the side of the square is 3+3 = 6
The area of the square is
A =s^2 = 6^2 = 36
The area of the circle is
A = pi r^2 where the radius is 3
(3.14) 3^2 =28.26
Subtract the area of the circle from the area of the square to get the shaded area
36-28.26 = 7.74 cm^2
Answer:
(0,-3)
Step-by-step explanation:
hi, with this we can just do substitution (substitute x for y+3)
6(y+3)-5y=15
evaluate
6y+18-5y=15
y+18=15
y=-3
then we plug that in
x=-3+3
x=0
Answer:
9pr = 2q^2
Step-by-step explanation:
28.
px^2 + qx + r = 0
If one root is A then the other root is 2A
We have A + 2A = -q/p and A*2A = r/p
So 3A = -q/p so A = -q/3p and A^2 = r/2p so A = √ (r / 2p)
Equating these 2 equations:-
-q/3p = √(r / 2p)
q^2 / 9p^2 = r / 2p
9p^2r = 2pq^2
9pr = 2q^2 (answer)
