Hey!
so first distribute the 5 to x + 4
5x+20 = 2x + 20 + 2x
combine 2x and 2x
5x+20 = 4x + 20
Now you want the constant and variable on different sides so subtract 4x to the other side
5x - 4x + 20 = 20
1x + 20 = 20
now subtract the 20 on the 1x + 20 side to the other side
1x = 0
divide by 1
0 divided by anything is 0
So x = 0
Hope this helps!
The require set (CUD)' and C'nD is {q, r, x, y} and Ø.
<h3>Set theory</h3>
Sets are elements arranged in a specific pattern or way. Given the expression below;
U= {f, k, q, r, s, x, y }
C={f, s,y}
D = {f,x)
CUD is the union of two sets and given as:
C U D = {f, s, y, k}
(CUD)' = {q, r, x, y}
For the set C'nD
C' = {k, q, r,x}
C' n D = Ø.
Hence the require set (CUD)' and C'nD is {q, r, x, y} and Ø.

Compare the values they have given you with the diagram. a, b and c are all sides of the triangle they want you to find the perimeter of. Knowing this, all you have to do is add a, b and c. h is not important because you don't count the altitude of a triangle when you calculate perimeter.
12 + 10 + 12 = 34
The perimeter of the triangle is 34 ft.

Answer:</h2>
The graph on the top left.
<h2>
Step-by-step explanation:</h2>
f(x) = 
That means that when x = 0...
f(0) = 
f(0) = -1 - 3
f(0) = -4
So, the function will have a point at (0, -4). We can eliminate the two graphs on the right.
When x = 1...
f(1) = 
f(1) = -4 - 3
f(1) = -7
So, the function will have a point at (1, -7). That corresponds to the graph on the top left.
