Answer:

4

Step-by-step explanation:

Since both of these numbers are negative, it means that the answer will be negative, since 2 negatives make a positive, since now you know that, you can easily do 32/8 which is 4.

-32/ -8 = 4

Check....

-8 * 4 = -32

-32 / 4 = -8

When there is a negative number and a positive number being multiplied or divided by, it will always result in a negative number.

Answer:

LCD = (x - 7)(x + 3)(x + 2)(x - 2)

Step-by-step explanation:

First, we factor each polynomial.

x^2 - 4x - 21 = (x - 7)(x + 3)

x^2 - 4 = (x + 2)(x - 2)

There are 4 different factors and none are in common, so the LCD is the product of all the factors.

LCD = (x - 7)(x + 3)(x + 2)(x - 2)

Answer:

(x+3)(x-7) & (x+2)(x-2)

Answer:

16

Step-by-step explanation:

Answer: 16

Step-by-step explanation:

4 to the second power is 4x4 and 4x4 is 16.

Answer:

a.) 1/2n 4=3−5/n b.) 1/2(n 4)=5/n−3 c.) 1/2(n 4)=3−5/n d.) 1/2n 4=5/n−3

Let's assume the number be n.

So, sum of number and four can be written as n+4.

Now one-half of n+4 will be .

Quotient of five and the number can be written as .

Now three less \frac{5}{n} can be written as \frac{5}{n} -3.

So, one-half the sum of a number and four is three less than the quotient of five and the number can be converted into equation as follows:

So, b is the correct choice.

Answer:

Option D

Step-by-step explanation:

(8x^2-9y^2-4x) +(x^2-3y^2-7x)

8x^2+x^2-9y^2-3y^2-4x-7x

9x^2-12y^2-11x

The sum of the polynomials is 4x² - 12y² - 11x. The correct answer is an option (D) 4x² - 12y² - 11x.

A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.

The polynomials are given as follows:

(8x² - 9y² - 4x) + (x² - 3y² - 7x)

By combining like terms, we can add the polynomials:

(8x² - 9y² - 4x) + (x² - 3y² - 7x)

= 8x² - 4x² - 9y² - 3y² - 4x - 7x

= 4x² - 12y² - 11x

Therefore, the sum of the polynomials is 4x² - 12y² - 11x.

Hence, the correct answer is option (D) 4x² - 12y² - 11x.

Answer:b

Step-by-step explanation:

Maynard is incorrect on the number line a is to the left of b thus a < b can be represented thus option (A) is correct.

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

As per the given number line,

If a number is going to the left of a number line then it will become lower and lower.

Since a is on the left of b so a < b.

It is also obtained that a is less than 0 so it will be negative while b will be positive since all negative value is less than positive thus a < b will be correct.

Hence "Maynard is mistaken since an is to the left of b on the number line, which can be expressed as a b".

Answer:

  (x^(1/2))^2 = x^(2/2) = x

Step-by-step explanation:

The square root of a number, when multiplied by itself, gives the original number.

  (√x)(√x) = x

The rule for exponents is that powers of the same base, when multiplied, will be the base to the sum of those powers.

  (a^b)(a^c) = a^(b+c)

Also, the first power of a number is that number itself.

__

  [tex]x^{\frac{1}{2}}\times x^{\frac{1}{2}}=x^{\frac{1}{2}+\frac{1}{2}}=x^1=x\\\\ \text{Compare to ...}\\\\ \sqrt{x}\times\sqrt{x}=x[/tex]

Answer:

Squaring and square root are inverses, so one should "undo" the other. That is, squaring the square root of a number results in the number. Using the power of a power rule, you multiply the exponents. Since a number to the first power is itself, the product of the exponents must equal 1. This means that the power of the square root must be the reciprocal of 2, or one half.

Answer: Either it is not hard to find four leaf clovers, or i would be lucky to find one.

Step-by-step explanation:

An assumption is any assertion or concept that is taken to be true and on which an argument or argument may be based.

From the argument is centered on the probability of finding a four leaf clover.

It is an already established fact that four leaf clovers are rear to come by so it would require a lot of luck to actually find one.
