Answer:

The top right answer choice is correct.

2.3 x 12 = 27.6

27.6 > 27.1

Step-by-step explanation:

Well first off, we know that:

1 foot = 12 inches

To compare the two, we first want to covert 2.3 feet into inches.

2.3 x 12 = 27.6 inches

Now that we have our two values, we need to decide which is greater than the other.

27.6 or 27.1

Both values have a decimal that shows tenths. In this problem, 6 tenths is larger than 1 tenth. Therefore:

27.6 inches > 27.1 inches

Heather can complete two problems in ten minutes, and when she started she had three problems done. Joel can complete three prob

Hunter-Best [27]

If Heather can do 2 in 10 minutes, then that means that she can do 12 in 1 hour. If Joel can do 3 in 15 minutes, then it means that he can do 12 in 1 hour. Add the number of problems they can do total and that will go between 30 and 50. It is just "less than", not "less than or equal to" because you want to know when the total number goes between the numbers.
Therefore, the correct answer must be 30 < 24x + 5 < 50.

Given:

$1. -3 x^{2}\left(4 x^{3}-7\right)\\$2. $(6 x-5)(2 x+3)$\\3. $(3 x-1)\left(x^{2}+5 x-2\right)$$

To find:

The product of the polynomials.

Solution:

1. $-3 x^{2}\left(4 x^{3}-7\right)$ $=-3 x^{2}(4 x^{3}) -3 x^{2}(-7)$

Multiply the numerical coefficient and add the powers of x.

$=-12 x^{5}+21 x^{2}$

2. $(6 x-5)(2 x+3)=6 x(2 x+3)-5(2x+3)$

Multiply each term of first polynomial with each term of 2nd polynomial.

Multiply the numerical coefficient and add the powers of x.

$=12 x^2+18x-10 x-15$

$=12 x^2+8x-15$

3. $(3 x-1)\left(x^{2}+5 x-2\right)=3 x(x^{2}+5 x-2)-1(x^{2}+5 x-2)$

Multiply each term of first polynomial with each term of 2nd polynomial.

Multiply the numerical coefficient and add the powers of x.

$=3x^{3}+15 x^2-6x-x^{2}-5 x+2$

Add or subtract like terms together.

$=3x^{3}+14 x^2-11x+2$

The answer for multiplying polynomials:

$1. -12 x^{5}+21 x^{2}$

$2. \ 12 x^2+8x-15$

$3. \ 3x^{3}+14 x^2-11x+2$

Annette [7]

$450 per week earns you $450 total per week, for $23,400 total
$115 per week earns you that plus 9.5% of $125,000, which is $11,875, plus $5,980 which is $17,855 total
There is a $5,545 difference, making the $450 a week a better deal
