In simplifying polynomials, we need to remember that only like terms can be added or subtracted to each other. Also, the order of solving the basic operators should be followed which is PEMDAS.

3x2y2 − 5xy2 − 3x2y2 + 2x2

The first and the thrid term is equal to zero thus the polynomial is:

− 5xy2 + 2x2

The polynomial has two terms with a degree of three.

What four factors were used to create this product game board 9,15,18,21,30,35,36,42,49

IgorLugansk [536]

To see what are the factors use, we write each of the numbers, as product of prime factors:

$9= 3 \cdot 3\\\\
15=3 \cdot 5\\\\
18= 2 \cdot 9 = 2 \cdot 3 \cdot3\\\\21= 3\cdot 7\\\\30=3 \cdot10=3 \cdot 2 \cdot 5\\\\35=5 \cdot7\\\\36=6\cdot6=2\cdot3\cdot2\cdot3\\\\42=6\cdot7=2\cdot3\cdot7\\\\49=7\cdot7
$

As we can see, the 4 factors used to produce the numbers in the list are {2, 3, 5, 7}

Answer: {2, 3, 5, 7}

An owner of a key rings manufacturing company found that the profit earned (in thousands of dollars) per day by selling n number

vovikov84 [41]

Answer:

The number of key rings sold on a particular day when the total profit is $5,000 is 4,000 rings.

Step-by-step explanation:

The question is incomplete.

An owner of a key rings manufacturing company found that the profit earned (in thousands of dollars) per day by selling n number of key rings is given by

$P=n^2-2n-3$

where n is the number of key rings in thousands.

Find the number of key rings sold on a particular day when the total profit is $5,000.

We have the profit defined by a quadratic function.

We have to calculate n, for which the profit is $5,000.

$P=n^2-2n-3=5\\\\n^2-2n-8=0$

We have to calculate the roots of the polynomial we use the quadratic equation:

$n=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\n= \frac{-2\pm\sqrt{4-4*1*(-8)}}{2}= \frac{-2\pm\sqrt{4-32}}{2} = \frac{-2\pm\sqrt{36}}{2} =\frac{-2\pm6}{2} \\\\n_1=(-2-6)/2=-8/2=-4\\\\n_2=(-2+6)/2=4/2=2$

n1 is not valid, as the amount of rings sold can not be negative.

Then, the solution is n=4 or 4,000 rings sold.

One number is 3 less than another number if their sum is 49

Musya8 [376]

One number is 26 the other is 23

x+y=49

Y=x+3,X (now substitute it in the equation)

x+3+x=49

2x+3=49

2x=46. X=23

Y=x+3. Y=23+3 =26 for checking 23+26=49
