The value of x is x
and x
Step-by-step explanation:
Factorisation is not possible in this case since the 2 pairs available will not be giving the same outcome as required in factorisation.
This is a quadratic equation
x² + x² – 3x – 3 = 0
2x² - 3x - 3 = 0
<u>Quadratic formula:</u>
a=2
b= -3
x= -3
= 
= 2.186
or
= 
= -0.686
Therefore, the value of x is,
x and x

Answer:
B. A water wheel in a dry river
Step-by-step explanation:
Work is said to be done when a force moves a body or an object through a certain distance in the direction of the force. Thus for work to be done, force and distance are required.
i.e Work done = Force x distance
It is measured in Joules.
Also, the work done by an object could be a measured of potential energy.
So that,
Work done = potential energy = mass x gravitational force x height
Considering the collage in the question, since the water wheel is in a dry river no work is done. Water wheel is a device that functions through the flow of water body, thus causing its rotation.
