Answer:

-5 is a root

Step-by-step explanation:

It would help to see any possible answers for this if this is a multiple choice question, but if a factor of f(x) is (x+5), then -5 must be a root of a function.

To find roots, set factor equal to zero and solve:

x + 5 = 0

x = -5

<h3>Answer:</h3>

28inch^2

<h3>Step-by-step solution:</h3>

Rectangle:

<em>[</em><em>L</em><em>e</em><em>n</em><em>g</em><em>t</em><em>h</em><em> </em><em>x</em><em> </em><em>B</em><em>r</em><em>e</em><em>a</em><em>d</em><em>t</em><em>h</em><em>]</em>

5 + 3 = 8inch

8 x 2.5 = 20inch^2

Right Triangle:

<em>[</em><em>1</em><em>/</em><em>2</em><em> </em><em>x</em><em> </em><em>B</em><em>a</em><em>s</em><em>e</em><em> </em><em>x</em><em> </em><em>H</em><em>e</em><em>i</em><em>g</em><em>h</em><em>t</em><em>]</em>

1/2 x 5 x 2 = 1/2 x 10

= 5inch^2

Left Triangle:

<em>[</em><em>1</em><em>/</em><em>2</em><em> </em><em>x</em><em> </em><em>B</em><em>a</em><em>s</em><em>e</em><em> </em><em>x</em><em> </em><em>H</em><em>e</em><em>i</em><em>g</em><em>h</em><em>t</em><em>]</em>

1/2 x 3 x 2 = 1/2 x 6

= 3inch^2

20 + 5 + 3 = <u>2</u><u>8</u><u>i</u><u>n</u><u>c</u><u>h</u><u>^</u><u>2</u>
