Discount prices/the discount
E.g.the new price of the book is 75 which has a discount of 75%
The original price = 75/0.75=100
The correct answer is the last set of numbers
Multiply entire equation by (x-2)(x+1) to get rid of the denominators That would lead to X(x+1)+(x-1)(x-2)=-1(x-2)(x+1)
Finally, using distributive property and foil, you would get x^2+x+x^2-3x+2=(-x^2+x+2).2x^2-2x+2=-x^2+x+23x^2-3x=0
3x(x-1)x=0 and x=1
Answer:
C is the answer
Step-by-step explanation:
Find the area of the whole circle, r=12cm
=pie× radius sq
=3.14×12×12
=<u>452.16cm sq</u>
The are of the smaller circle, r=6cm
=same formula
=3.14×6×6
=<u>113.04cm sq</u>
<u>Subtract</u><u> </u><u>them</u><u> </u><u>to</u><u> </u><u>find</u><u> </u><u>the</u><u> </u><u>area</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>shaded</u><u> </u><u>region</u><u> </u>
452.16 - 113.04
=339.12
