Answer:
Step-by-step explanation:
Because we have to rewrite this equation in the format 
, we have to divide, or factor to find basic terms,
Expanding the value of k(x), we have 
. We see that each term can be divisible by 4, so we can factor out 4 to get
Now, we have two different terms getting multiplied. We can separate the two to get 
Because we are multiplying 4 by the other term, this is represented by 
Now, we can just set f(x) and g(x) to these functions:
Now, just to make sure, we can plug a value into k(x) and the same value into f(g(x)). Plugging in 1, we have (2(1)+4)2 as 2(2+4), which is 2(6) = 12.
Plugging 1 into f(g(x)), we can evaluate g(1) first, to get 1 + 2 = 3. Now, f(3) = 4(3)= 12, which is the same for k(x).

Answer:9
Step-by-step explanation:
-2x+8=-10
-2x=-18
X=9
10 times the sum of 2 and 1 is represented by the following expression:
10 x (2 + 1)
10 x is ten times, and (2 + 1) the sum of 2 and 1, "10 times the sum of 2 and 1".
<span>for an equilateral triangle you need to know that:
- Sides are equal a = b = c (figure 1)
- Each angle is 60 degrees (figure 1)
- Height led from the top of the base of the triangle divide into two identical special right triangles on Measures angles 30,60,90 degrees. (figure 3)
</span>triangle with angles : 30°,60° , 90°<span> is the length of the sides :
1 a = a catheus (red)
2 b = a</span>√3 catheus (red)
<span>3 c = 2a hypotenuse
</span><span>the product of the hypotenuse of the triangle is the value of the surface of an equilateral triangle
</span>
P = a*b = (1/2*68cm*√3)*(1/2*68cm) = (34√3cm) * (34cm) = 1156√3cm²
