You draw perpendicular bisectors to find the center of a circle circumscribed about a triangle. Hook me up with 5 stars :)
if x = 3
3 > -1, and so you use the x² formula.
Plug in 3 for x
x² = (3)²
Simplify
3² = 3 x 3 = 9
9, or (A), is your answer
hope this helps
The problem wants to calculate the percentage error of the measurement of 7cm and if the measurement is uncertain we could use the formula of getting the error by margin of error over measurement time 100% and base on the data, the error would be if the margin error is 7.5 is 107 %. I hope you are satisfied with my answer
Because Jamaal is not running against anyone for class treasurer he will be the only 1 therefore the answer is 1. According to e2020 the answer is 1 also.
X+7.4=49.8
-7.4 -7.4
x=49.8-7.4
x= 42.4
