<h2>○=> <u>Correct option</u> :</h2><h2>\color{plum}\tt\bold{(B)}</h2><h3>○=> <u>Steps to derive correct option</u> :</h3>

We know that :

\color{hotpink} \tt \: circumference \: of \: a \: circle\color{plum} = 2\pi r

So, let the diameter of this circle be x.

Which means :

=\tt2  \times \pi  \times r

=\tt 2 \times x \times \pi = 12\pi

=\tt 2x\pi = 12\pi

=\tt x =  \frac{12}{2}

= \tt \: x = 6 \: m

Thus, the radius of the circle Robert drew = 6 m

Since the circle in option B has a radius of 6 m, it is the circle Robert drew.

▪︎<em>Therefore, the correct option is (B)</em>

Which Question Has roots of x= -2 and x
vazorg [7]

See explanation below.

Explanation:

The 'difference between roots and factors of an equation' is not a straightforward question. Let's define both to establish the link between the two..

Assume we have some function of a single variable

x

;

we'll call this

f

(

x

)

Then we can form an equation:

f

(

x

)

=

0

Then the "roots" of this equation are all the values of

x

that satisfy that equation. Remember that these values may be real and/or imaginary.

Now, up to this point we have not assumed anything about

f

x

)

. To consider factors, we now need to assume that

f

(

x

)

=

g

(

x

)

⋅

h

(

x

)

.

That is that

f

(

x

)

factorises into some functions

g

(

x

)

×

h

(

x

)

If we recall our equation:

f

(

x

)

=

0

Then we can now say that either

g

(

x

)

=

0

or

h

(

x

)

=

0

.. and thus show the link between the roots and factors of an equation.

[NB: A simple example of these general principles would be where

f

(

x

)

is a quadratic function that factorises into two linear factors.
