(x4)(3x2 - 2)(4x2 + 5x)
= (12x3 - 2x4) (4x2 + 5x)
= 48x5 + 60x4 - 8x6 - 10x5
= - 8x6 + 48x5 - 10x5 + 60x4 ...//
= 2x4 ( - 4x2 + 24x - 5x + 30 )
= 2x4 ( - 4x2 + 19x - 30 ) ...//
Answer:
Step-by-step explanation:
This is a proportion question. You can take either of the other sides besides N to calculate the ratio. You need to use corresponding sides.
Here is the proportion
N/5 = 18/8
Multiply both sides by 5
N = 5 * 18/8
N = 90/8
N = 11.25
Answer:

Step-by-step explanation:
Let x and y represent the prices of grandstand and general admission tickets, respectively. The problem statement describes two relations.
.. 5x +3y = 2230
.. 6x +6y = 3180
These can be solved graphically to find
.. x = 320
.. y = 210
The price for a grandstand ticket is $320.
The price for a general admission ticket is $210.
