Answer: The answer is 3n + 2
Step-by-step explanation: You will have to combine like terms:
=−n + −4 + 4n + 6

=3n + 2
3x^2=375
x^2=125
x=11.18
c or d, they say the same thing
Answer:
Step-by-step explanation:
y = -1/3x + 2
m1 = -1/3
Slope of the perpendicular line = -1/m1 = -1 ÷
= 
Equation of the required line : y = mx +b
y = 3x + b
Plugin x = 2 and y 10 in the above equation
10 = 3*2+ b
10 = 6 +b
10 - 6 = b
b = 4
Equation: y = 3x + 4
All you would do is divide 9.99/15 to get how much one pound costs.
