Given:

(x+2) is a factor of polynomial f(x).

To find:

The correct statement.

Solution:

If (x-c) is a factor of polynomial f(x), then c is a zero of the polynomial and f(c)=0.

We have, (x+2) is a factor of polynomial f(x).

On comparing (x-c) and (x+2), we get

c=-2

It means, -2 is a zero of the polynomial f(x) and the value the polynomial at x=-2 is 0, i.e.,

f(-2)=0

Therefore, the correct option is d.

A banana weighs 3/8 kg. An apple weighs 2/3 kg. Determine a reasonable estimate for the weight of both fruits?
garik1379 [7]

Answer:

\frac{25}{24}

Step-by-step explanation:

The computation of the reasonable weight for both the fruits is given below:

Since the weight of the banana is \frac{3}{8} kg

And, the weight of the apple is \frac{2}{3} kg

So, the reasonable weight would be

= Weight of the banana + weight of the apple

= \frac{3}{8} + \frac{2}{3}\\\\= \frac{9 + 16}{24}  \\\\= \frac{25}{24}

<u>Let's take this step-by-step:</u>

  • Part (a)

         The mathematical name of this shape is a <u>right trapezoid </u>

              ⇒ <em>It is a trapezoid since the image shows a quadrilateral that </em>

<em>                   has two parallel sides and two non-parallel sides. It is a right </em>

<em>                   trapezoid because it has two rights angles</em>

  • <em>Part (b)</em>

<em>           </em>The cube has <u>6</u> faces

               ⇒ <em>faces are the individual flat surfaces of an object</em>

<em>                    ⇒by looking at a picture of a cube, we see it has 6 sides</em>

<em>                        ⇒ (I attached an image of a cube below)</em>

Hope that helps!
