Evaluate the following expression.
1/8^2 I NEED HELPPPP!!!!!!!!

Maybe 0.7 the way you put it made it confusing

The expression that can be factored into the form (ax + b)(ax - b), where a and b are rational numbers, is 4n² - 81.

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.

Here,

A.
4n² - 81,
This can be factored as (2n - 9)(2n + 9), which is of the form (ax + b)(ax - b).

B.

2n² - 49,
This can be factored as (n - 7√2)(n + 7√2), but not in the form (ax + b)(ax - b).

C.

2n² + 49:

This cannot be factored into the form (ax + b)(ax - b) using rational numbers. We can factor it over the complex numbers as (n + i√49/2)(n - i√49/2), where i is the imaginary unit, but this does not satisfy the conditions of the problem.

D.

4n² + 81,
This cannot be factored into the form (ax + b)(ax - b)

Therefore, the expression that can be factored into the form (ax + b)(ax - b), where a and b are rational numbers, is 4n2 + 81.

Answer:

[tex]1\dfrac{3}{32}\ \text{inches}^2[/tex]

[tex]4\dfrac{1}{4}\ \text{inches}[/tex]

Step-by-step explanation:

w = Width of a stamp = [tex]\dfrac{7}{8}\ \text{inch}[/tex]

l = Length of a stamp = [tex]1\dfrac{1}{4}\ \text{inch}[/tex]

Area is given by

[tex]A=lw\\\Rightarrow A=\dfrac{7}{8}\times 1\dfrac{1}{4}\\\Rightarrow A=\dfrac{7}{8}\times \dfrac{5}{4}\\\Rightarrow A=\dfrac{35}{32}\\\Rightarrow A=1\dfrac{3}{32}\ \text{inches}^2[/tex]

The area of each stamp is [tex]1\dfrac{3}{32}\ \text{inches}^2[/tex]

Perimeter is given by

[tex]P=2(l+w)\\\Rightarrow P=2(\dfrac{7}{8}+\dfrac{5}{4})\\\Rightarrow P=2\times \dfrac{17}{8}\\\Rightarrow P=\dfrac{17}{4}=4\dfrac{1}{4}\ \text{inches}[/tex]

The perimeter of each stamp is [tex]4\dfrac{1}{4}\ \text{inches}[/tex].

Answer:

Option B is correct.

Step-by-step explanation:

Total bill = $48

Tip = 20%

Amount of tip = 20% of 48

Amount = [tex]\frac{20}{100}*48[/tex]

Amount = 0.2 * 48

Amount = $9.60

Total bill with tip = 48 + 9.60 = $57.60

Dividing by 2 as they are spliting the bill.

Each pays = [tex]\frac{57.60}{2}=28.80[/tex]

Therefore,

Option B is correct.

Answer:

5, 12, 19, 26, 33

Step-by-step explanation:

This is an arithmetic sequence since there is a common difference between each term. In this case, adding 7 to the previous term in the sequence gives the next term. In other words, an=a1 + d(n − 1) .

Arithmetic Sequence:  d=7

This is the formula of an arithmetic sequence.an=a1 + d(n-1)

Substitute in the values of

a1=5 and d=7. an=5 + (7) (n − 1)

Simplifly each term : an=5 + 7n − 7

Subtract  7  from 5.

an=7n − 2

The solution for x of the inequality x-c/d > y (for d > 0) is x > d * y + c.

Here,

To solve the inequality for x, we'll isolate x on one side of the inequality:

Given inequality: (x - c) / d > y

First, we'll multiply both sides of the inequality by d to get rid of the fraction.

Remember that since d > 0, we don't need to reverse the inequality:

d * [(x - c) / d] > d * y

Next, the d on the left side cancels out, and we have:

x - c > d * y

Now, to isolate x, we'll add c to both sides of the inequality:

x - c + c > d * y + c

x > d * y + c

So the solution for x is x > d * y + c.
