Factor completely a^2-ab-12 b^2

1 answer:

6 0

In order to factor this, you need to look at the coefficient of the last term which is -12. After that, you need to think of two factors of this number that would yield to -1 (which is the coefficient of the second term) when added or subtracted. You will get -4 and 3 (-4 + 3 = -1). Therefore, the expression would become (a – 4b)(a + 3b). This expression is the complete factors of the expression given.

Note: This is applicable when the coefficient of the first term is 1.

Calculate the pay for the following day of a weekly time card given a wage of $14/hr

xxTIMURxx [149]

Answer: $122.50

Step-by-step explanation:

We know the difference between the time the employee clocked in and clocked out = 1200 - 0800 = 4 hours

The next clock in and out = 17:30 - 12:45 = 4 hours, 45 minutes.

These times combined = 8 hours, 45 minutes

$\frac{45}{60}$ minutes in an hour = $\frac{3}{4}$ of an hour.

The total time worked was 8 $\frac{3}{4}$ hours.

Multiply 8.75 × $14 = $122.50

Answer: $ 290 thousand

Step-by-step explanation:

Given : According to a certain central bank from 2000 to 2016 the average price of a new home in a certain region increased by 62 % to $470 thousand.

Let X be the the average price of a new home in 2000 .

Then , the 62 % increase in price is given by :-

$x+0.62(x)=x(1+0.62)=1.62x$
