A would be the right answer since cubing is taking the number to the 3rd power, so for this question you would have to take the square root by 3
Answer: $2
==================================
Since 3 pencils and 1 notebook that costs $6 cost $12 in total:
3p + 6 = 12
3p = 12 - 6
3p = 6
p = 6÷3
p = 2
Therefore, the cost of each pencil is $2
The coordinates of point A is (0, - 4).
Start with the origin (0) and go down 4 units).
And obtuse angle is greater than 90°
It would be 5.29 since there are 100 centimeters in 1 meter, you just divide. 529/100=5.29
or just move the decimal place over 2 spots to the left
