The perimeter of an object is all of its sides added up. So it gives you the length and widths of the shape.
A. X + 4 + X + X + 4 + X = 34. But we can simply that even further. To 4X + 8 = 34

B. So solve that you would first Subtract 8 from each side. You then get 4x = 26
X = 13/2
13/2 is your answer. You can simplify this to 7.5 but ask your teacher if you can leave it as 13/2 because it will save you a lot of time on a test.

A: 34-8 = 26/4 = 6.5 so x=6.5

If m(x)=x 5/x-1 and n(x) = x – 3, which function has the same domain as (m*n)(x)

Tatiana [17]

Answer:
m(x) has the same domain as (m*n)(x)

Explanation:
1- For m(x):
m(x) is a fraction. This means that the denominator cannot be zero, otherwise, the fraction would be undefined.
The denominator of m(x) would be zero at x = 1.
This means that the domain of m(x) can be any real number except 1

2- For n(x):
The value of x in n(x) can be any number. This is because there is no value that would make n(x) undefined.
This means that the domain of n(x) is all real numbers

3- For (m*n)(x):
(m*n)(x) = m(x) * n(x) = $\frac{x-5}{x-1} *(x-3) = \frac{(x-5)(x-3)}{(x-1)}$

We can note that the product is also a fraction. This means that the denominator cannot be zero.
The denominator here will be zero at x = 1.
This means that the domain of (m*n)(x) is all real numbers except 1.
This is the same as the domain of m(x)

Hope this helps :)

Solve. 5m+72=−2m+52 Drag and drop the answer into the box.

olasank [31]

5m + 72 = -2m + 52
5m + 72 + 2m = -2m + 52 + 2m
7m + 72 = 52
7m + 72 - 72 = 52 - 72
7m = -20

7m/7 = -20/7
m = -20/7
