Answer:
22cm²
Step-by-step explanation:
radius of smaller circle= 7/2=3.5cm
area of smaller circle=π×3.5=11cm²
area of bigger circle=π×10.5(radius is 7 plus 3.5)=33cm²
area of shaded area=33-11=22cm²
30 is A to the second power 31 is X to the first power 32 is just M
First step: x= ± √ 121
Second step and correct answer: x= ± 11
Because: x^2 = x= ± √
4 x 27 = 108 and 4 + 27 = 31... I don't think there is any pair of numbers that would equal -31. So the answer would be 4 and 27. Good luck! Hope this helped!!
Is the x2 squared or is it just 2x.
