Answer:

x^2(5x + 7)(5x - 7)

Step-by-step explanation:

Considering you need a negative and a positive to get a negative number, the second and fourth options are wrong. The first option still needs to factor out x^2, which is why x^2(5x + 7)(5x - 7)  is correct.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

3x+2y=8

5x+2y=12

Now, solving both using method of Elimination Method

3x - 5x = 8-12

-2x= -4

x = -4/ -2

x= 2

and, 3x+ 2y = 8

3(2) + 2y = 8

6  + 2y = 8

2y = 8-6

2y = 2

y = 2/2

y= 1

Hence, the value of x=2 and y=1.

Kelly has a pool in her backyard, and she wants to build a fence around the entire area. Kelly's backyard is 14 meters wide and 15 meters long. It costs $6.63 per meter to install a wooden fence. How much would it cost to put a wooden fence around Kelly's backyard?

Answers

Answer:

$384.54

Step-by-step explanation:

Dimensions of the backyard is 14 m by 15 m

The length of the fence is the perimeter of the backyard.

P = 2(l +w)P = 2(15 + 14) = 2(29) = 58 m

One meter of the fence costs $6.63

Cost of the entire fence is:

58*$6.63 = $384.54

Answer:

perimeter of backyard=2(15+14)=58m

it cost

1m=$6.63

58m=$6.63×58=$384.54

therefore it cost

$384.54 to put a wooden fence around Kelly's backyard.

Kimberly is deciding between two cell phone plans. The first plan has a $50 sign-up
fee and costs $20 per month. The second plan has a $30 sign-up fee and costs $25 per
month. After how many months will the costs be the same for the two phone plans?

Answers

Answer:

2month and 2 weeks

Step-by-step explanation:

We are told that the first plan has a $50 sign-up

fee and costs $20 per month.

let the number of months be x, and the total cost be y

y=20x+50---------1

The second plan has a $30 sign-up fee and costs $25 per

let the number of months be x, and the total cost be y

y=30x+25---------2

Equate the two equations we have

20x+50=30x+25

solve for x, collect like terms

50-25=30x-20x

25=10x

divide both sides by 10

x= 25/10

x=2.5 months

x= 2month and 2 weeks

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The expressions are,

⇒ y = 1/2x - 6

⇒ x = - 4

Now, We can simplify the expression for y as;

⇒ y = 1/2x - 6

Put x = - 4;

⇒ y = 1/2 × - 4 - 6

⇒y = - 2 - 6

⇒ y = - 8

Thus, The solution to the system of equations is,

⇒ (- 4, - 8)

You need to make at least 360 wraps for a party. You can make 9 wraps per minute.

How long will it take you to make the number of wraps you need?
In two or more complete sentences write and solve an inequality for the situation and explain how you will solve the inequality.

Answers

Answer:

It will take 40 minutes for me to make the 360 wraps that I need.

9x ≥ 360 ⇒ x ≥ 40

Step-by-step explanation:

I have to make at least 360 wraps for a party.

I can make 9 wraps per minute.

So, it will take  minutes for me to make the 360 wraps that I need.

If I work for x minutes to make wraps, then I will be able to make 9x wraps.

So, the inequality that models the given condition is

9x ≥ 360

⇒ x ≥ 40 {Dividing both sides by 9}

Therefore, I need to work at least 40 minutes to reach my goal. (Answer)
