If you would like to simplify the following expression <span>(28x - 7y) + (32x + 52y), you can do this using the following steps:

</span>(28x - 7y) + (32x + 52y) = <span>28x - 7y + 32x + 52y = 28x + 32x - 7y + 52y = 60x + 45y
</span>
The correct result would be B. <span>60x + 45y.</span>

Prove the polynomial identity.

Ronch [10]

Answer:

The answer to your question is: 2, 4, 5, 1 , 3

Step-by-step explanation:

The first line is the second

(3x² - 6)² - (3x²)² = 36(1 - x)(1 + 1)

The second line is the forth

9x⁴ - 36x² + 36x² - 9x⁴ = 36(1 - x)(1 + x)

The next line is the fifth

36 - 36x² = 36(1 - x)(1 + x)

The next line is the first

36(1 - x²) = 36(1 - x)(1 + x)

The last line is the third

36(1 - x)(1 + x) = 36(1 - x)(1 + x)

Answer:

Step-by-step explanation:

Take the area of the yard and subtract from it the area of the pool. In quadratic form, the area of the pool is

$2x^2-x-28$

Subtracting the area of the pool from the area of the yard:

$3x^2-14x-5-(2x^2-x-28)$

Since the negative in front of the parenthesis will change the signs inside:

$3x^2-14x-5-2x^2+x+28$

Combine like terms to get the area left after the pool goes in:

$x^2-13x+23$

Netta bought n shirts from the Walmart. Walmart charges $9 per shirt. Later the same day, netta bought n more shirts from amazon

Ipatiy [6.2K]

Answer:

$T(n)= 17n + 5$

Step-by-step explanation:

We are given the following in the question:

Number of shirts bought from Walmart = n

Cost of one shirt at Walmart = $9 per shirt

Total cost of shirt at Walmart =

$=\text{Number of shirts}\times \text{unit cost}\\=9n$

Number of shirts bought from Amazon = n

Cost of one shirt at Amazon = $8 per shirt

Shipping fee for entire order = $5

Total cost of shirt at Amazon =

$=\text{Shipping fee} + (\text{Number of shirts}\times \text{unit cost})\\=5 + 8n$

Total amount spent by Netta on shirts in one day =

Total cost of shirt at Walmart + Total cost of shirt at Amazon

$T(n)= (9n) + (5+8n)\\T(n)=9n + 8n + 5\\T(n)=17n + 5$

is the required expression where T(n) is the total cost and n is the number of shirts purchased at Walmart as well as Amazon.
