![\bold{x=-4\pm\sqrt{46}}](https://tex.z-dn.net/?f=%5Cbold%7Bx%3D-4%5Cpm%5Csqrt%7B46%7D%7D)
Step-by-step explanation:

To find the rate, you need to divide the change of distance by the change of time
(1716-1236)/(18-8)
=480/10
=48
Therefore, his rate is 48m/s
- Reducing the fraction 14/21 to its lowest term is 2/3.
- Reducing the fraction 10/12 to its lowest term is 5/6.
- Reducing the fraction 6/16 to its lowest term is 3/8.
<h3>What is a fraction?</h3>
A fraction can be defined as a numerical quantity which isn't expressed as a whole number. This ultimately implies that, a fraction is simply a part of a whole number.
<h3>The parts of a fraction.</h3>
In Mathematics, a fraction comprises two (2) main parts and these include the following:
Next, we would reduce each of the fractions to its lowest term by dividing with a common divisor.
Fraction = 14/21
Dividing by 7, we have:
Fraction = 2/3.
Fraction = 10/12
Dividing by 2, we have:
Fraction = 5/6.
Fraction = 6/16
Dividing by 2, we have:
Fraction = 3/8.
