Answer:

  • (2b - 1)(2a + 3n)

-----------------------------------------------

Given polynomial

  • 4ab + 6bn - 2a - 3n​

Factorize it as below:

4ab + 6bn - 2a - 3n​ =    

(4ab - 2a) + (6bn - 3n) =         Regroup        

2a(2b - 1) + 3n(2b - 1) =           Factorize each group using common factors

(2b - 1)(2a + 3n)                       Factorize using common factor

Answer:

(2b-1)(2a+3n)

Step-by-step explanation:

Given expression:

4ab+6bn-2a-3n

Factorize the first two terms and the last two terms separately:

\implies 2b(2a+3n)-1(2a+3n)

Factor out the common term (2a + 3n):

\implies (2b-1)(2a+3n)

The simple interest earned on a deposit of 4000 at 5% for 120 days
Ymorist [56]

Answer:A = $4,066.00

Step-by-step explanation:

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year.

Putting time into years for simplicity,

120 days / 360 days/year = 0.33 years.

Solving our equation:

A = 4000(1 + (0.05 × 0.33)) = 4066

A = $4,066.00

The total amount accrued, principal plus interest, from simple interest on a principal of $4,000.00 at a rate of 5% per year for 0.33 years (120 days) is $4,066.00.

* Hopefully this helps:) Mark me the brainlliest:)!!

Daniel is planning a 6-night road trip. It will cost $310 for transportation, $275 for food, and $70 per night for a hotel room.
Anna11 [10]

Answer:

Daniel must tutor 160 hours

Explanation:

310+275+70= 655

655×6= 3930 (he needs this amount of $)

(Daniel gains $20 per hour)

20×160= 3200

3200+745= 3945

3945 > 3930

Daniel has enough for the trip.

Where did I get 160?

Well, I was just trying out numbers and multiplying it by 20

The numbers I tried: 100, 150, 156, 159 & 160 but only 160 fit with the answer.

If it was just one night road trip he would've just needed $655, but since it's a 6-night road trip I multiplied it by 6.

Hope this helped!
