Answer: B) 54 feet

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Perimeter of a rectangle: 2L + 2 W

Where:  

L= Length

W= Width

Replacing with the values given:

Perimeter: 2(15)+2(12)=30+24=54 feet

In conclusion, they need 54 feet. The correct option is option B).

Feel free to ask for more if needed or if you did not understand something.

ladessa [460]

Answer:

120

Step-by-step explanation:

As x goes from 1 to 2, y increases by 4 from 4 to 8

As x goes from 2 to 3, y increases by 4 from 8 to 12

We increase by 4 each time

The formula for an arithmetic sequence is

an = a1+d(n-1)

where a1 is the first term which is 4

d is the common difference or the number we add each time which is 4

n is the term we are looking for which is 30

a30 = 4 +4 (30-1)

a30 = 4+4(29)

       = 4+116

      = 120

Polygon with three interior angles whose sum 180 degrees
mojhsa [17]

Answer:

Triangle

Step-by-step explanation:

A triangle has three vertexes, and therefore three interior angles. Those angles also sum to 180 degrees because of the formula (n-2)*180, where n is the number of sides that a polygon has. Plugging in 3, you get  1\cdot 180, or just 180 degrees. Hope this helps!

If f(x)=4x^2 and g(x)=x+1, find (fog)(x)
iren [92.7K]

Answer: The value of (f_\circ g)(x)  is  4(x+1)^2  .

Step-by-step explanation:

Given: f(x) = 4x^2 \text { and } g(x) = x+1

To find: (f_\circ g)(x)

As we know it is composition function which means that  g(x) function is in f(x) function.

So we have

(f_\circ g) (x) =  f[g(x)]

\Rightarrow( f_\circ g)(x)= f(g(x)) = 4(g(x))^2

Now substitute the value of g(x) we get

(f_\circ g)(x)= 4(x+1)^2

Hence, the value of (f_\circ g)(x)  is  4(x+1)^2  .
