Factor this trinomial completely.
WITCHER [35]

Answer:

Option C. (2x+3)(6x – 5) is the correct answer.

Step-by-step explanation:

Given polynomial(trinomial) is:

12x^2 + 8x - 15

The given trinomial is quadratic. Factorization will be as follows:

Multiplying the co-efficient of x^2 and the constant results in 180. We have to make factors of 180 in such a way that their sum of difference is equal to the co-efficient of x.

The required factors are 18 and 10

So,

=12x^2+18x-10x-15\\=6x(2x+3)-5(2x+3)\\= (6x-5)(2x+3)

Hence,

Option C. (2x+3)(6x – 5) is the correct answer.

How many months does it take to earn $180 in interest on an investment of the principal is $5000 and the interest rate is 2%?
12345 [234]

Answer:

months = 6.67

Step-by-step explanation:

time in years = interest / (principal amount x rate)

time in y = 180 / (5000 x 0.02)

time in y = 180 / 100

time in months = 12 / 1.8

months = 6.67

What represents 200 million<br>​
sattari [20]

Answer:

200 million represents a very large number and therefore it is not commonly encountered in the history of the people of God. However, is reflected in the number of silver coins annually paid by the vinedressers who farmed King Solomon's vineyards (ie, 1,000 x 1,000 x 200).
