Answer:
Multiply 4(3+x)
Step-by-step explanation:
First: 4*3=12 so, 12+3x=9
12+3x=9
-12
3x=-3
divide by 3
Solution: x=-1
Answer:
a) (-2,-1) b) (-3,0) & (-1,0)
Step-by-step explanation:
For the first part, the turning point is simply where the graph curves. We can see that that happens on (-2, -1).
For the second part, the roots of the equation are simply when the graph crosses the x-axis. This happens twice, at (-3,0) and (-1,0)
I assume this an algebraic expression..sooo the variable L will represent the number of books in the library, and five times the number of books in the library would be 5L
