Answer:

(x^4y^6+1)(x^8y^{12}-x^4y^6+1)

Step-by-step explanation:

We have been given an expression x^{12}y^{18}+1 and we are asked to factor our given expression.

We will use sum of cubes formula to factor our given expression.

a^3+b^3=(a+b)(a^2-ab+b^2)

Upon using power rule of exponents a^{bc}=(a^b)^{c}, we can write:

x^{12}=(x^4)^3

y^{18}=(y^6)^3

We can write 1 as 1^3 as 1 raised to any power equals 1.

Now we are ready to apply sum of cubes formula.

(x^4y^6)^3+1^3=(x^4y^6+1)((x^4y^6)^2-x^4y^6+1^2)

Upon simplifying right side of our equation we will get,

(x^4y^6)^3+1=(x^4y^6+1)(x^{4*2}y^{6*2}-x^4y^6+1)

(x^4y^6)^3+1=(x^4y^6+1)(x^8y^{12}-x^4y^6+1)

Therefore, after factoring our given expression we get (x^4y^6+1)(x^8y^{12}-x^4y^6+1).

Rates like $ per channel is a slope, "m". The added fee is a constant so it's the intercept "b".
y = mx + b

So for the first problem (9)
(a)
y = total cost in dollars
x = number of premium channels
y = 16x + 44
(b) when x = 3 channels
y = 16(3) + 44
y = 92 $

the second problem (10)
(a) every 4 years the tree grows by 12-9=3 ft
So the unit rate or slope will be 3 ft per 4 yrs, (3/4). You can see this also by solving for slope "m" using the given points (4,9) and (8,12).

x = number of years
y = height of tree in ft
y = (3/4)x + b
use one of the points to find the y-intercept "b".

9 = (3/4)(4) + b
9 = 3 + b
9 - 3 = b
6 = b
y = (3/4)x + 6

(b) when x = 16
y = (3/4)(16) + 6
y = 12 + 6
y = 18 ft

Amanda spent a total of 70 minutes competing her chores this week. Write and solve an equation to represent the number of minute
gtnhenbr [62]

Answer:

28 minutes spent in washing the dishes.

Step-by-step explanation:

Given the table

Chore             time in minutes

Sweeping           42

Dishes                  ?

Amanda spent a total of 70 minutes competing her chores this week

Total of 70 minutes spent

42 minutes spent in sweeping . to find the number of minutes Amanda spent in washing the dishes , subtract 42 minutes from the total time spent

let x be the number of minutes spent washing the dishes

42+x=70

To solve for x , subtract 42 from both sides

42+x=70\\x= 70-42\\x=28

28 minutes spent in washing the dishes.
