Answer:

${(x - 6)}^{2}$

Step-by-step explanation:

$= {x}^{2} - 12x + 36 \\ = {x}^{2} - (6 + 6)x + 36 \\ = {x }^{2} - 6x - 6x + 36 \\ = x(x - 6) - 6(x - 6) \\ =(x - 6)(x - 6) \\ = {(x - 6)}^{2}$

Mr. Erickson will be living in the forest

aliina [53]

<em /> $\huge{\boxed{60\ \text{ft}^{3}}}$ <em />

<em>We will assume the tent is in the shape of a triangular prism.</em>

The volume of a triangular prism can be found with the following formula, where $b$ is the width at the base, $h$ is the height, and $l$ is the length.

$V=\frac{1}{2}bhl$

Substitute in the known values.

$V=\frac{1}{2}*5*3*8$

Simplify — use multiplication.

$V=\frac{5}{2}*3*8$

$V=\frac{15}{2}*8$

$V=\frac{120}{2}$

Simplify — use division.

$V=\large{\boxed{60\ \text{ft}^{3}}}$

The volume — or in this case, the amount of living space — is $60\ \text{cubic feet}$ .

Find the area of the triangle

Helga [31]

Answer:

The answer is

$\huge \boxed{54 \: \: {units}^{2} }$

Step-by-step explanation:

Area of a triangle is given by

$A = \frac{1}{2} \times base \times height \\$

From the question

base = 18

height = 6

So we have

$A = \frac{1}{2} \times 18 \times 6 \\ = 9 \times 6 \\ = 54 \: \: \: \: \:$

We have the final answer as

<h3>54 units²</h3>

Hope this helps you
