23x-13=2(x+2)
First you would distribute the 2 into the parenthesis
It will look like this after: 23x-13=2x+4
Then you would subtract 2x on both sides because u have to get the x's on one side
It will look like this after:21x-13=4
Then you would add 13 to both sides
It will look like this after: 21x=17
Then you would divide 21 on both sides
Your final product is 21/17

<u><em>The question in English is:</em></u>
From the general term, calculate the first 4 terms.
(Consider that you must assign values to the variable n)
we have
step 1
Calculate the first term
For n=1
step 2
Calculate the second term
For n=2
step 3
Calculate the third term
For n=3
step 4
Calculate the fourth term
For n=4
therefore
the first 4 terms are
Answer:
270kilometers
Step-by-step explanation:
To find the distance, all you have to do is the speed · time
In these types of distance time and word problems, you multiply the other factors, 90 and 3, The time(T) · The speed(S)
So. 90(S) · 3(T) = 270(D)
The area between the two functions is 0
<h3>How to determine the area?</h3>
The functions are given as:
f₁(x)= 1
f₂(x) = |x - 2|
x ∈ [0, 4]
The area between the functions is
A = ∫[f₂(x) - f₁(x) ] dx
The above integral becomes
A = ∫|x - 2| - 1 dx (0 to 4)
When the above is integrated, we have:
A = [(|x - 2|(x - 2))/2 - x] (0 to 4)
Expand the above integral
A = [(|4 - 2|(4 - 2))/2 - 4] - [(|0 - 2|(0 - 2))/2 - 0]
This gives
A = [2 - 4] - [-2- 0]
Evaluate the expression
A = 0
Hence, the area between the two functions is 0
