Answer:
Step-by-step explanation:
Okay!
A graph representing the function :
f(x)=x(x+2)
I will describe the graph for you!
the points on this graph are : (-3,3),(-2,0),(-1,-1),(0,0),(1,3)
the graph also creates a U shape!
x=7
expand 4(x+5): 4x+20
2x+34=4x+20
subtract 34 from both sides
2x+34-34=4x+20-34
2x=4x-14
subtract 4x from both sides
2x-4x=4x-14-4x
-2x=-14
divide both sides by -2
-2x/-2=-14/-2
All you need o divide 3,300 by 50
3300
÷ 50

<u>Remove "x" and add</u>
-2 + 9 = 7
<u>Add "x" back</u>
7 -----> 7x
Note: When adding/subtracting problems like these remove "x" and then add/subtract normaly. When you get your answer put x back.
