We are asked in the problem to determine the value of x in the equation <span>4x² + 2x = 7 using completing the square method. in this case,
</span><span>4x² + 2x = 7
x2 + 0.5 = 1.75
(x + 0.25)^2 - 0.0625 = 1.75
</span>(x + 0.25)^2 = 1.8125
<span>x+0.25=1.3462
</span>x1 =1.0963
x2 =-1.5962
The answer is C, because to find IQR you have to find the difference (subtract) of the first and third quartile
-9 is farther from 0 on the number line.
That would be 1/8 times 288, so the answer would be 36 part time workers.
