If by 4x(2) you mean 4x to the power 2 or 4x^2...it can be solved in the following way
f(x)=4x^2-4x-3
=4x^2+2x-6x-3
=2x(2x+2)-3(2x+2)
=(2x-3)(2x+2)
Therefore x=3/2 or x=-2/2=(-1)
Answer:
76.8
Step-by-step explanation:
The mean is the sum of the values divided by the total number of values.
63+73+92+63+93 / 5 =

Answer:
Graph B
Step-by-step explanation:
Answer:
Profit earned by Randi on her last snow shoveling and salting job= $ 60
Let number of hours spent by Randi on that day while working as a shoveler and salter = x hours
Writing the statement in terms of inequality
→ Number of hours worked= Amount of profit earned
→ x=60
→If profit is less than $60.00, then Number of hours will be less.
→If Profit is more i.e greater than $60.00, Number of hours will be more.
