You have 7 lines and per 3 lines you're charged $14.50. 7 divided by 3 is 2.33333333. 14.50 X 2 = $29. Now you solve for the unit price ( the cost per one line and multiply that by 2 ) So the unit price is about $4.83. $4.83 x 2.33333 = $11.27. The total cost would be about $40.27.
I hope this helps :)
a) (x + 3)( X + 5 )
x( x + 3 )+ 5 (x + 3 )
x square + 3 X + 5 x + 15
X square + 8 x + 15
b)( 3 x minus 2)( X + 4)
x (3 x - 2 )+ 4(3 X - 2 )
3 x square - 2 X + 12 x -8
3 X square + 10 x - 8
c)x(x - 7)
x square - 7 x
Answer:
10.45
Step-by-step explanation:
A=pi10^2*63/360-10*10 sin63/2=3.14*6300/360-50*0.89
A=3.14*17.5-44.5=54.95-44.5=10.45
or if I do not complete pi=3.14
A=17.5 pi-44.5
