Answer:
D. 2(x - 1)(x – 3)
Step-by-step explanation:
4(x2 – 2x) – 2(x2 – 3)
We would first of all expand the expression given
This becomes
= 4x2 - 8x - 2x2 + 6
Rearrange to enable us simplify
4x2 - 2x2 - 8x + 6
= 2x2 - 8x + 6
Factorize
2 (x2 - 4x + 3)
factorizing further using the factors of 3 that add up to -4
2(x2 - x - 3x + 3)
pick out the common factors
2(x(x-1) -3(x-1)
2(x-1)(x-3)
Option D. 2(x - 1)(x – 3) is right
Answer:
4200 tickets of 
and 1800 tickets of 
were sold
Step-by-step explanation:
Given:
Tickets are sold at price and .
Let Number of tickets sold at price be 
.
Let Number of tickets sold at price be 
.
Theater has maximum capacity of 6000 seat.
Hence,
Total revenue to be generated is 
Now Multiplying equation 1 by 40 we get,
Now Subtracting equation 2 by equation 3 we get,
Now substituting value of x in equation 1 we get,
Hence a total of 4200 tickets of and 1800 tickets of were sold
Answer:
A. P = 9x + 2
Step-by-step explanation:
Perimeter is all the sides lengths added together.
Step 1: Set up equation
