The value of x is x=2.57338 and x=−0.906718
<h3>What is equation?</h3>
An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.
Given:
3x²-5x-7=0
Using the discriminant method,
a = 3, b = -5, and c = -7
x= -b± √b²-4ac / 2a
x= 5 ± √25 + 84/ 6
x= 5± √ 109
Hence, x=2.57338 and x=−0.906718

The total number of pencils is 2,160. When estimating to the nearest hundredth one gets 2,200, which is an underestimate.
The advantage of underestimating is that your answer is more accurate than an overestimate.

Answer:
F. None of the above
Step-by-step explanation:
A cone is produced by rotating the shape about line m.
The height of the cone will be 0.5 because it's perpendicular to the base.
Since the height is 0.5, the answer is not A or B.
The circular base is formed by the line split into two "1"s. Each "1" is the radius, together, the diameter of the base.
Since r = 1, the answer is not C.
Since d = 2r = 2(1) = 2, the answer is not D.
∴ The answer is none of the above, F.
