Answer:

(2l + 2w) + (a + b + c)

Step-by-step explanation:

The formula for the perimeter of a rectangle is

P = 2l + 2w

so if you substitute, it becomes

P = 2(12) + 2(2)

= 24 + 4

= 28

For the perimeter of a triangle the correct formula would be

P = a + b + c

The missing side in the triangle is 3 because 15 - 12 is 3.

If you substitute, it becomes

P = 2 + 3 + 6

P = 11

If we add both perimeters together we get the full perimeter of the figure which is

28 + 11 = 39

I am not sure if you wanted the answer as well but just in case :)

Answer:

$57.2\ ft$

Step-by-step explanation:

we know that

The formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)

In this problem

The tangent of angle of 5 degrees is equal to the quotient of "rise over run"

Let

y ----> the rise of the ramp

x ----> the run of the ramp

$tan(5^o)=\frac{y}{x}$

we have

$y=5\ ft$

substitute and solve for x

$tan(5^o)=\frac{5}{x}$

$x=\frac{5}{tan(5^o)}$

$x=57.2\ ft$

Which student correctly used guess and check to determine the unknown number?

Alenkasestr [34]

<h2>Explanation:</h2><h2></h2>

Hello! Remember you need to write complete questions in order to get good and exact answers. Here we know nothing about the students so I can only help you providing the correct steps to find <em>the product of a number and eight is 104:</em>

<em />

Let that number be $n$ , then the statement can be written in a mathematical language as follows:

$n\times 8=104 \\ \\ \\ \text{Dividing both sides by 8:} \\ \\ \frac{n\times 8}{8}=\frac{104}{8} \\ \\ \boxed{n=13}$

Finally, <em>the unknown number is 13</em>
