Mumz [18]

Answer:

$Total = 625x^3 + 125x^2 + 125x$

Step-by-step explanation:

Given

$Flowers = 25x^2 + 5x + 5$

$Unit\ price = 5x$

Required

The total price for 5 days

First, calculate the total for a day.

$1\ day = Unit\ price * Flowers$

$1\ day = 5x * (25x^2 + 5x + 5)$

Open bracket

$1\ day = 125x^3 + 25x^2 + 25x$

For 5 days, the total will be.

Total = days * sales of a day

So, we have:

$Total = 5 * [ 125x^3 + 25x^2 + 25x]$

$Total = 625x^3 + 125x^2 + 125x$

Answer: option 1.

$log_{4} x$

x f(x)

4 log (4) 4 = 1 ... because 4^1 = 4

16 log(4) 16 = 2 .... because 4^2 = 16

64 log (4) 64 = 3 .... because 4^3 = 64

Factor completely 3x2 - 21.

VMariaS [17]

3x² - 21

Factor 3 from both terms:

3 (x² - 7)

To me, that's as far as you should need to go. But if you want to get
completely carried away, you could go one step further, since you have
the difference of two squares:

3 (x + √7) (x - √7)

Of course, there's no end now, because the last binomial could be
considered another difference of two squares, so you'd have to
factor that too:

3 (x + √7) (√x + ⁴√7) (√x - ⁴√7)

but to me, this would be nonsense.
