Answer:

$\boxed{ \bold{ \boxed{ \sf{12 {x}^{2} - 13x - 14}}}}$

Step-by-step explanation:

$\sf{(3x + 2)(4x - 7)}$

Use the distributive property to multiply each term of the first binomial by each term of the second binomial

$\longrightarrow{ \sf{3x(4x - 7) + 2(4x - 7)}}$

$\dashrightarrow{ \sf{12 {x}^{2} - 21x + 8x - 14}}$

Collect like terms

$\longrightarrow{ \sf{12 {x}^{2} - 13x - 14}}$

Hope I helped!

Best regards! :D

Answer:

12 $x^{2}$ + 29x - 14

Step-by-step explanation:

(3x+2)(4x-7)

Multiply out 3x first then 2

(3x * 4x) - (3x * -7) + (2 * 4x) + (2 * -7)

12 $x^{2}$ - (- 21x) + 8x + ( -14)

12 $x^{2}$ + 21x + 8x - 14 Combine like terms

12 $x^{2}$ + 29x - 14

Tyra buys 14 gallons of gas for $35. How could she figure out how much 1 gallon of gas cost

defon

Answer:

The cost of 1 gallon is $2.5

Step-by-step explanation:

Given

Cost of 14 gallons = $35

Required

Determine the cost of 1 gallon

From the given parameters, we have:

$14\ gallons = \$35$

Divide both sides by 14

$\frac{14\ gallons}{14} = \frac{\$35}{14}$

$1\ gallon = \frac{\$35}{14}$

$1\ gallon = \$2.5$

Hence,

The cost of 1 gallon is $2.5

Shaka and ajani playa a game shaka scores 30%of maximum points and misses the record by 15 points ajani gets 40% of maximum pint

stellarik [79]

Step-by-step explanation:

First, we should focus on their records and percents.

Shaka: 30%, -15 points.

Ajani: 40% +35 points.

When we subtract 35 and -15, we get the difference of 50.

We know 10% is 50 point difference, 20% is 100 point difference, 30% is 150 point difference, etc.

But that's not correct.

It has to be in the Negatives.

It cannot be positive under 30%.

Since 30% is -15 points, we subtract 50 for 20%, then another 50 for 10%.

Our Correct work is:

0% = -0, 10% = -115, 20% = -65, (30% = -15, 40% = 35.)

- We are correct.

Then, since we are correct, we keep going.

30% = -15, 40% = 35, 50% = 85, 60% = 135, 70% = 185, 80% = 235, 90% = 285, 100% (Or Maximum Point): 335.

Therefore, the Maximum Point is 335 points.

Best of Luck to you!

Use set notation to denote the elements, subsets, and complements of the following given sets.

vlabodo [156]

Answer:

N = {13, 15, 17, 19} is the correct answer.

Step-by-step explanation:

We are given with the following details:

N is the set of odd natural numbers.

N contains the elements which are greater than 11 and less than 21.

To write: The set notation for the elements of set N.

Solution:

First of all, let us see what are odd natural numbers.

Natural numbers are the positive integers i.e. {1,2,3,4, ........ }

Odd Natural numbers are the natural numbers which leave remainder as 1 when divided by 2 i.e. {1,3,5,7,9,11,13, ...... 21, 23, 25, 27.....}

Here, set N is odd natural numbers greater than 11 (so 11 will not be included) and less than 21 (so 21 will not be included). Odd natural numbers between 11 and 21 will be included.

So the answer will be N = {13,15,17,19}.
