For this, we use the FOIL method of expanding brackets; start by multiplying the FIRST terms of each bracket together to get xx=x^2. Next multiply the OUTSIDE elements, ie the first element in the first bracket and the last in the second, giving x(-5)=-5x. Then comes the INSIDE elements, giving 4x=4x, and finaly the LAST elements of each bracket, giving 4(-5)=-20. Adding all these terms together gives us our answer; x^2+4x-5x-20, which can be simplified to x^2-x-20.
Hope this helps!
The hourly wage increase each employee receives each year depends on their number of years of service. Every three years of service means an increase of $0.50 per hour. So, employees that have been with the company for less than three years can expect to receive an increase of $0.50 per hour. Employees that have been with the company for at least three years, but less than six years can expect an increase of $1.00 per hour. Employees that have been with the company for at six years, but less than nine years, receive an increase of $1.50 per hour. And, employees of at least nine years, but less than twelve years receive an increase of $2.00 per hour.

Answer:
C. 1
Step-by-step explanation:
f(2) simply means x = 2.
We are trying to find the y-value when x = 2.
According to the graph, when x = 2, y = 1.
Therefore, f(2) = 1.
Answer:
let 3:2 be 3x& 2x
perimeter =40
2(l+b)=40
2(3x+2x)=40
5x=40/2
x=20/5=4cm
length=3x=3×x=3×4=12cm
breadth =2x=2×4=8cm
area of rectangle =l×b=12×8=96cm²
