If there are n rows
And if each row has m seats.
Then the total number of seats shall be n × m.
Here
Number of rows = (c+8)
And number of seats in each row = (4c-1)
Using the concept
Total number of seats
= (c+8)(4c-1)
FOILing or Distributing we get
= c(4c) + c (-1) + 8(4c) +8 (-1)
= 4c² - c + 32 c -8
Combining like terms
=4c² +31c - 8
The expression for total number of seats = 4c² + 31c -8
Answer:
2(x - 9.46)(x + 2.54)
Step-by-step explanation:
2(x² - 12x + 24)
since there are no factors that multiply to 24 and add to -12 then i used the quadratic formula to get:
6+2
, 6-2
- 9 ≤ x ≤ 7
the domain is the values of x on the x- axis that define y = f(x)
y is defined for all values of x in the stated domain
Answer:
350
Step-by-step explanation:
To start, solve each equation for y.
1st equation) 3x+y=-2, subtract 3x, y=-3x-2
2nd equation) 2y-6x=4, add 6x, 2y=6x+4, divide by 2, y=3x+2
3rd equation) 2y=-6x-8, divide by 2, y=-3x-4
Now, for lines to be parallel, their slope must be the same. Using the equation y=mx+b where m is slope, you can determine the slope of each line.
1st line) y=-3x-2, slope of -3
2nd line) y=3x+2, slope of 3
3rd line) y=-3x-4, slope of -3
Comparing these lines, you can see that only lines 1 and 3 have the same slope, making those your parallel lines.
