Answer:
D
Step-by-step explanation:
We know that we are adding the two expressions because the question says "sum" which means that we need to add. Let's combine like terms. We know that x + 2x = 3x and 5 + 3 = 8 so the answer is 3x + 8.
F(x)= (x+4) ^{2} -13 is the answer

Answer:
No. They are not equivalent.
Step-by-step explanation:
=> 
Therefore, 3/5 and 1/2 are not equivalent.
Hoped this helped.
Answer: They are similar many ways.
Step-by-step explanation:
1. There is a law that guides both of them. Because each has a strick law.
2. They both need practice. Practice they say makes one perfect. When u practice both of them, you become familiar on how to use them.
3. The brain has to read meaning to either of the two to be able to be able to learn a pattern of learn.
4. Both language and functions are systems. They are made of different parts, language is made up of different words while function is made up of axioms which theorems.
Answer:
CD = 14 cm; DE = 21 cm
Step-by-step explanation:
The perimeter is the sum of side lengths (in centimeters), so ...
CD + DE + CF + EF = 55
CD + DE + 8 + 12 = 55 . . . . . . . substittute for CF and EF
CD + DE = 35 . . . . . . . . . . . . . . subtract 20
___
The segment DF is a diagonal of the rhombus, so bisects angle D. That angle bisector divides ΔCDE into segments that are proportional. That is, ...
CD/DE = CF/EF = 8/12 = 2/3
___
So, we have two segments whose sum is 35 (cm) and whose ratio is 2 : 3. The total of "ratio units is 2+3=5, so each must stand for a length unit of 35/5 = 7 (cm). The sides are ...
CD = 2·7 cm = 14 cm
DE = 3·7 cm = 21 cm
<em>Check</em>
CD + DE = (14 +21) cm = 35 cm . . . . . matches requirements
