The correct answers are:

Composite numbers can be written as the product of prime factors.

Explanation:

A composite number is a number that has factors other than 1 and itself.

A prime number is a number whose only factors are 1 and itself.

Every composite number can be broken down into a series of prime numbers. You begin with something you know the composite number is divisible by, and keep dividing it down, listing the prime factors as you go. This is called prime factorization.

Yes, the blank numbers that can be written as a product of blank factors are called the prime factorization of a number. It can also be composite numbers where it can be written also as the product of prime factors.

Answer:

Extraneous variable.

Step-by-step explanation:

This variable is not seen to work on its own directly in a lot of cases, they are explained to be occurrences or certain factors that are seen to influence the process of the experiment that are not independent variable. In different surveys of studies, it is said to sometimes posses a negative effect on the data consequentially. Many surveys and research has also shown that some of these variables can be controlled while also some of them cannot be controlled.

Solve the equation. x2 18x 81 = 25 a. 14, 4 b. –4, –14 c. 14, –14 d. –4, 4

Snowcat [4.5K]

Answer:

The answer is the option B

$-4,-14$

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^{2}+18x+81=25$

$x^{2}+18x+56=0$

$a=1\\b=18\\c=56$

substitute in the formula

$x=\frac{-18(+/-)\sqrt{18^{2}-4(1)(56)}} {2(1)}$

$x=\frac{-18(+/-)\sqrt{100}} {2}$

$x=\frac{-18(+/-)10} {2}$

$x1=\frac{-18+10} {2}=-4$

$x2=\frac{-18-10} {2}=-14$

Solve system by elimination -9x+7y=22 9x-5y=-26

alisha [4.7K]

Answer:

The solution would be (-4, -2)

Step-by-step explanation:

To find this simply add the two equations together.

-9x+7y=22

9x-5y=-26

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

2y = -4

y = -2

Now we have the y value, we can solve for the x value.

9x-5y=-26

9x-5(-2)=-26

9x+10=-16

9x=-36

x = -4
