Answer:
In centimeters, it would be 40.64 centimeters.
To solve this equation you need to find the value of x.
You can do this by using inverse operations.
and getting x alone.
x/4=5
the opposite of division is multiplication so we multiply 5 by 4
x=5*4
we now have x alone and must solve the rest of the equation
5*4=20
There for x=20

I hope this helped:) If you have any questions pleas comment and i will do my best to answer and/ or explain :)
Answer:
Step-by-step explanation:
This is a reading question. You have to know what all the terms mean.
B: is the first one you have to think about. All real solutions. Is that the answer, or do you have to think about it more. The key word is solutions. So that takes in A. So B is the answer.
A is the second best answer. Any solution has to be on the blue line. The blue line is the visual record of what works in B. Well, why not pick A? It is because B is more general, and it includes A.
C More than whole numbers solve this question. The line is continuous.
D There are negative solutions as well. Not the answer.
Step-by-step explanation:
l= 3x+2cm
b=4cm
Perimeter of the rectangle= 68cm
Now, according to the formula, the perimeter of a rectangle= 2(l+b)
Therefore,
2(l+b)=68
2{(3x+2)+(4)}=68
2{3x+2+4}=68
2{3x+6}=68
6x+12=68
6x=68-12
6x=56
x=56/6
x≈9.33
In order to cross-check this answer, we compute in the values so therefore,
3x+2=3(9.33)+2=27.99+2=29.99≈30
Now, substituting this value in the formula we get,
2(30+4)= 68
The reason for cross-checking was to re-assure because of the decimal value of 9.33, that is why I approximated the expression to 30 in order to get the exact value of 68. otherwise using the decimal value of 9.33 computes an answer of 67.98 which off by a difference of 0.2.
The common factors of 36 and 72 are:
1, 2, 3, 4, 6, 9, 12, 18, and 36.
All of them go into both 36 and 72.
