Answer:

Given,

Area of the Square = ( x² - 10x + 25 ) m²

We have to find: Length of the side of the square.

Let s be the side of square.

We find length of side of the by using factorization.

According to the question,

s² = x² - 10x + 25

s² = x² - 5x - 5x + 25

s² = x( x - 5 ) - 5( x - 5 )

s² = ( x - 5 )( x - 5 )

s² = ( x - 5 )²

Taking square root on both sides we get,

s = x - 5

Therefore, Expression that represents the length of one side of the square is x - 5.

Step-by-step explanation:

Answer:

2x - 8

Parts of an equation:

2 - coefficient

x - variable

8 - constant

The number 2 is not a coefficient in the expression. FALSE.

The expression has three terms. FALSE. two terms only: 2x & 8

The variable in the expression is x. TRUE

The number 2 is a constant in the expression. FALSE

The expression has one variable term. FALSE. 2x is term but it's a combination of a number and a letter. Variable term is letter only.

Hello.

The coefficient is the number before a variable (letter)

The constant is also a number.

What's the difference between a constant and a coefficient?

Well, a coefficient is always before a variable, and a constant is just a number (without any variables next to it)

In this case, the variable is x, the number before x is 2, and 8 is the constant.

Therefore, 2 is the coefficient in this expression.

I hope it helps.

Have a nice day.

Step-by-step explanation:

The area of the rectangular picture frame that is 5/6 feet long and [tex]1\frac{2}{3}[/tex] feet wide is  [tex]1\frac{7}{18}[/tex] ft²

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

Given that, Jackie bought a rectangular picture frame that is 5/6 feet long and [tex]1\frac{2}{3}[/tex] feet wide.

We need to find its area,

We know that, the area of the rectangle = length × width

Here,

Length = 5/6 ft

Width =  [tex]1\frac{2}{3}[/tex] ft

Area =  [tex]1\frac{2}{3}[/tex]  × 5/6

= 5/3 × 5/6

= 25/18

= [tex]1\frac{7}{18}[/tex] ft²

Hence, the area of the rectangular picture frame that is 5/6 feet long and [tex]1\frac{2}{3}[/tex] feet wide is  [tex]1\frac{7}{18}[/tex] ft²

Step-by-step explanation:

3x+8 = 35

3x = 27

x = 9

Hope this helps :)

Step-by-step explanation:

Here, (3x + 8)° and 35° are vertically opposite angles which are equal, therefore,

3x + 8 = 35

3x = 35 - 8

3x = 27

x = 27/3

x = 9

Answer:

width = 9/2 inches, length = 18 inches

Step-by-step explanation:

Step-by-step explanation:

l = length

w = width

l×w = 81 in²

l = 2w + 9

we can use the identity of the second equation in the first equation :

(2w + 9)×w = 81

2w² + 9w = 81

2w² + 9w - 81 = 0

the general solution to such a quadratic equation is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = w

a = 2

b = 9

c = -81

w = (-9 ± sqrt(9² - 4×2×-81))/(2×2) =

= (-9 ± sqrt(81 + 648))/4 =

= (-9 ± sqrt(729))/4 = (-9 ± 27)/4

w1 = (-9 + 27)/4 = 18/4 = 9/2 in

w2 = (-9 - 27)/4 = -36/4 = -9

a negative solution for a side length does not make any sense, so, width = 9/2 in is the only valid solution.

l = 2w + 9 = 2×9/2 + 9 = 9+9 = 18 in

so, the last answer option is correct.

Answer:

To have a right triangle, the side lengths should make Pythagorean theorem true

Since the hypotenuse is always the longest side of a triangle, the biggest number will be c

Set the rest two numbers as a and b

Use a^2 + b^2 = c^2 to plug in the numbers

If you get true equation, meaning you have the same number on the left and right sides of equation, then it is going to create a right triangle

Answer:

72 sq ft

Step-by-step explanation:

A square room means ecah side is equal. so 12*12= 144.

12 times 6 (for the height)= 72 sq ft

Answer:

72 square feet

Step-by-step explanation:

if the area of the floor is 144 and square, that means that the sides are the same length. 12 * 12 = 144 so the length is 12.

the height of the room is 6 so you multiply 12 and 6 and you get 72

Answer: 5 divided by 1/2 is 10

Step-by-step explanation:

5 x (1/2) = 10/1 = 10

Multiplying the first fraction by the reciprocal value of the second fraction is the same as dividing two fractions. The first step is to get the reciprocal of the second fraction (reverse the numerator and denominator, reciprocal of 1/ 2 is 2/ 1 ). Multiply the two numerators after that. Then add the two denominators together.

To put it another way, five divided by one-half equals 10.

b<16

Step-by-step explanation:

b/4<4. Multiply 4 on both sides. b has to be less than 16.

Step-by-step explanation:

64% = 64/100 = 16/25 = 0.64

1/8 = 0.125 = 12.5%

1.4 = 140% = 140/100 = 100/100 + 40/100 = 1 2/5

2 3/4 = 2.75 = 275%

8% = 8/100 = 2/25 = 0.08

Answer:2

Step-by-step explanation:

You need to remember these 3 rules when working with multiplication:

Negative number x Negative number = positive number

Negative number x Positive number = Negative number

Positive Number x Positive Number = Positive Number

With that in mind, we see in this equation we are multiplying negative number x positive number = negative number

And we also know 7*2=14 so we know A = 2 and we also know (since A is a positive number) 2 will be postitive:

So the equation will look like this:

-7 x 2 = -14

Therefore A = 2

Answer:

A

Step-by-step explanation:

Answer:

(4, 3 )

Step-by-step explanation:

2x - 4y = - 4 → (1)

2x + y = 11 → (2)

subtract (2) from (1) term by term to eliminate x

(2x - 2x) + (- 4y - y) = - 4 - 11

0 - 5y = - 15

- 5y = - 15 ( divide both sides by - 5 )

y = 3

substitute y = 3 into either of the 2 equations and solve for x

substituting into (2)

2x + 3 = 11 ( subtract 3 from both sides )

2x = 8 ( divide both sides by 2 )

x = 4

solution is (4, 3 )
