Answer:

$(7k - 6) (4k^{2} + 7)$

Step-by-step explanation:

$28k^{3} - 24k^{2} + 49k - 42$

$= (28k^{3} - 24k^{2}) + (49k - 42)$

$= 4k^{2} (7k - 6) + 7 (7k - 6)$

$= (7k - 6) (4k^{2} + 7)$

Answer:

$(4k^2+7)(7k-6)$

Step-by-step explanation:

Factor each half of the expression separately:

$4k^2(7k-6)+7(7k-6)$

Since both 4k² and 7 are being multiplied by (7k-6), we can combine them to get:

$(4k^2+7)(7k-6)$

What is n? Stick around for more points

N is a variable in algebra. Variables are letters that represent unknown numbers. Variables can be any letter of the alphabet.

Here's how to use n in an algebraic equation:

5 + n = 12

To find what N represents, let it be the only thing on the left side of the variable:

5 -5 + n = 12 - 5

n = 7

Ignore outside work find all missing variables and measures of each angle**

borishaifa [10]

Answer:

y= 18

42°

x=60

60°

Step-by-step explanation:

because of vertical angles theorem, 2y+6=8y-102

add 102 to 6

2y+108=8y

subtract 2y from 8y

108=6y

y= 18

now plug in to each equation for angles

2(18)+6= 42°

8(18)-102= 42°

now I dont think you can solve for x and y in an equation. 3x=180

divide 3 from 180

180/3 = 60

x=60

plug 60 into 3x=180 and get 180°.

angles for x are 180°

if I'm incorrect on the X value someone please correct me.

I hope this helps!❤

The price of trade Suppose that Portugal and Germany both produce beer and olives. Portugal's opportunity cost of producing a cr

fiasKO [112]

Answer: Both 4 barrels and 7 barrels of beer per crates of olives will allow both Germany and Portugal to gain from trade.

Step-by-step explanation: For every 1 crate of olives produced by Portugal, they will not be able to produce 3 barrels of beer in return. Therefore, for portugal to trade a crate of olives for barrels of beer more than 3 means they are gaining on the trade, in this case, they gain 1 (option A) and 4(option B) extra barrels of beer for every crate of olive traded with Germany. Likewise Germany gains in both cases because any exchange of barrels of beer that is less than 11 barrels of beer to a crate of olives is a gain for Germany. Therefore both 4 barrels and 7 barrels for a crate of olives will lead to both countries gaining.

MATH

Scrat [10]

The sum of the lengths of the tables and the total length of overhang

give the length of fabric that Devon needs.

Response:

The total yards of fabric needed to make the table runners is<u> 12 yd</u>.

<h3>How can the given dimensions be added to obtain the length of fabric needed?</h3>

The given parameters are;

Length of the small tables = 6 feet

Length of the long tables = 10 feet

Length of overhang on each end = 8 inches

Number of small tables = 12

Number of long tables = 2 × 12 = 24

Required:

The yards of fabric needed to make the table runners.

Solution;

The total number of tables = 12 + 24 = 36

Length of overhang for each table = 8 inches + 8 inches = 16 inches

Sum of the length of the overhang = 36 × 16 inches = 576 inches

From the given unit conversion factors, we have;

Sum of the length of overhang = 576 inches ÷ 12 inch/feet = 48 feet

Length of the tables = 12 × 6 feet + 24 × 10 feet = 312 feet

Total length of table runner = 312 feet + 48 feet = 360 feet

Length of table runner needed = 360 feet ÷ 3 feet/yd = <u>120 yd.</u>
