I need help with this one math question please!
den301095 [7]

Answer:

see explanation

Step-by-step explanation:

Assuming the fractions are being multiplied

Factorise the denominators of both fractions

x² - 3x - 10 = (x - 5)(x + 2)

x² + x - 12 = (x + 4)(x - 3)

The product can now be expressed as

\frac{x-5}{(x-5)(x+2)} × \frac{x+2}{(x+4)(x-3)}

Cancel (x - 5) and (x + 2) on the numerators/ denominators, leaving

\frac{1}{(x+4)(x-3)} = \frac{1}{x^2+x-12}

The possible ways to complete a multiple-choice test consisting of 19 questions, with each question having four possible answers
LekaFEV [45]
Let's say there were 3 questions with four answer choices each. That would mean there were 4*4*4 = 16*4 = 64 different ways to answer.

Extend this example out to 19 questions instead of 3. You'll get
4^19 = 4*4*4*...*4*4 = 274,877,906,944
The last value is one big number (not four numbers)
The large number is the answer

note: 4^19 means we have 19 copies of '4' being multiplied together. The three dots mean "continue the pattern". On your paper, you should somehow indicate to your teacher that there are 19 copies of '4' being multiplied.

Renting a tent from the party supply store costs $100 for the insurance fee and $50 for each hour rented. Write an algebraic exp
igomit [66]

Insurance Fee = $100

Hours = h

Cost per hour = 50

Required

Determine an algebraic expression

The expression is as follows:

Expression = Insurance Fee + Cost per hour * number of hours

Expression = 100 + 50 * h

Expression = 100 + 50h

The coefficient in the question is the number of hours (h)

The sales tax in your city is 4.4%, point, 4, percent, and an item costs $3dollar sign, 3 before tax. How much tax would you pay
adell [148]

We are given an item cost before tax = $3.

Sales tax on item = 4.4% of the actual cost.

We are given actual cost = $3.

Therefore, 4.4 % of 3 = 0.044 × 3 = $0.132.

We need to round it to the nearest hundredth or cent that is upto two decimal places.

0.132 could be round to 0.13.

<h3>Therefore, $0.13 tax would you pay on that item on the given item cost $3.</h3>
