69
Step-by-step explanation:
The third option, 100*
making it an abtuse triangle
If incorrect, sorry
First, let's move combine like terms:
-5y + 8y = 6 + 2 -12.
3y = -4.
y = -4/3
Answer:
46p
Step-by-step explanation:
42*1.09=45.78
45.78 rounded up is 46p
Area shaded = Area big circle- Area of small circle;
200 pi= pi•(2x)^2 -pi•6^2;
200pi= pi•4x^2 -pi•36;
200pi=pi•4(x^2 -9) divide both sides by 4pi;
50=x^2 -9; So x=sqrt(59)~7.68cm
