Factorise <br>16x²y+8xy all divided by 32xy+16y

Fed [463]

Answer:

3x^2+4x/16x+8

Step-by-step explanation:

6x²y+8xy/32xy+16y

Factor the top and bottom

2xy(3x+4)/16y(2x) -This is the most it can be factored but there is also another way (I'm not sure which one you're looking for)

The problem is that this is not simplified so in order to cancel things out the factored number should be the same.

2y(3x^2+4x)/2y(16x+8)

Cancel out 2y

3x^2+4x/16x+8

At Noise Pollution Cellular, plan A is $30.00 per month and $5.00 for every gigabyte of data. Plan B is $50.00 per month and $2.

Dafna1 [17]

First we define variables.We have then:D: monthly data.C: total cost.
For Plan A:
C = 5D +30
D: [5, 8]
We evaluate for D = 8
C = 5 (8) +30
C = 40 + 30
C = 70 $
For Plan B:
C = 2D +50
D: [5, 8]
We evaluate for D = 8
C = 2 (8) +50
C = 16 + 50
C = 66 $
Answer:
the best choice for him is plan B:
C = 2D +50

P Parentheses first

E Exponents (ie Powers and Square Roots, etc.)

MD Multiplication and Division (left-to-right)
