Answer:

The Answer Is That "The Greatest Common Factor Of The Terms Is 1."

Step-by-step explanation:

Took The Test.

The polynomial is factorized and greatest common factor of the terms is 1

Brackets should be expanded in the following ways to factorize an expression

For an expression of the form A = a ( b + c ) , the expanded version is given by A = ab + ac, i.e., multiply the term outside the bracket by everything inside the bracket

For an expression of the form A = ( a + b ) ( c + d ) , the expanded version is given by A = ac + ad + bc + bd, in other words everything in the first bracket should be multiplied by everything in the second.

Given data ,

Let the polynomial be represented as A

Now , the value of A is

A = 30x² + 40xy + 51y²    be equation (1)

Now , the expression can be factorized as

The factors of 30 = 1 , 2 , 3 , 5 , 6 , 15 and 30

The factors of 40 = 1 , 2 , 4 , 5 , 8 , 10 , 20 and 40

The factors of 51 = 1 , 17 , 51

Therefore , the greatest common factor is 1

Hence , the factorized form of the equation is A = 30x² + 40xy + 51y²

Answer:

  C.  26

Step-by-step explanation:

The two marked angles are "vertical angles." They are congruent.

  x +20 = 3x +8 . . . . . congruent angles have the same measure

  12 = 2x . . . . . . . . . subtract x+8 from both sides

  6 = x . . . . . . . . . divide by 2

  ∠PTQ = (x+20)° = (6+20)° = 26°

Answer:

Solutions given:

we have

<RTS=PTQ[vertically opposite angle are equal]

so

3x+8=x+20°

3x-x=20-8

2x=12

x=12/2=6

x=6

m<PTQ=6+20=26°

Answer:

Between 20% and 80%,,,

Step-by-step explanation:

There is no way to really explain it.

Answer:

DB = 20 cm

Step-by-step explanation:

Given:

║AB = 12 cm (represented by 'a' leg)

║AD = 16 cm (represented by 'b' leg)

║DB =  x cm (hypotenuse represented by 'c' leg)

These formulas are used to solve for a missing side length:

║a = [tex]\sqrt{(c^2 - b^2)}[/tex]

║b = [tex]\sqrt{(c^2 - a^2)}[/tex]

║c = [tex]\sqrt{(a^2 + b^2)}[/tex]

Because we are solving for side length c, we will be using the third formula.

║c = [tex]\sqrt{(a^2 + b^2)}[/tex]

║c = [tex]\sqrt{(12^2 + 16^2)}[/tex]

║c = [tex]\sqrt{(144 + 256)}[/tex]

║c = [tex]\sqrt{400}[/tex]

║c = 20

Therefore, the value for side length DB should be:

║DB = 20 cm

Let the length of the side of the square being cut out equal x

The length of the box would be 4.5 - 2x

The width of the box would be 3 -2x

Volume = (4.5 -2x) * (3-2x) * x

Simplify to:

V = 4x^3 - 15x^2 + 13.5x

B See picture: The greatest volume would be the point of the highest curve.

x = 0.589 y = 3.565, Rounded to the nearest tenth x = 0.6

Process: entered the equation from A into Desmos. The Y value would be the volume, so found where the volume was the highest and then found the related x value.

C) X is the side length of the corner squares being cut out, which would also be the height of the box. The Y value is the volume of the box.

Step-by-step explanation:

"A processing machine crushes 3 1/4 kilograms of dried fruits in 3/4 minutes.

What is the rate, in kilograms per minute, at which the machine crushes dried fruits?"

All you're doing here is finding the unit rate at which the machines crushes the fruit. This boils down to dividing the amount it can crush (3 + 1/4 kg) by the time it takes to do the crushing (3/4 min):

(3 + 1/4 kg) / (3/4 min)

We can omit the units, just remember everything is measured in kilograms per minute. So we want to simplify the expression,

(3 + 1/4) / (3/4)

Write the numerator as an improper fraction:

3 + 1/4 = 12/4 + 1/4 = 13/4

(since 12 = 3*4)

Then

(3 + 1/4) / (3/4) = (13/4) / (3/4)

Multiply this by 1 = 4/4. In other words, multiply both the numerator and denominator by 4. This eliminates the fractions in either part, and you get the answer:

(13/4) / (3/4) * 4/4 = (13/4 * 4) / (3/4 * 4) = 13/3

So in one minute, the machine can crush 13/3 kg ≈ 4.333 kg of dried fruit.

Step-by-step explanation:

the can is shaped like a cylinder

first step is to find the radius and then multiply the figure by 2

volume of a cylinder = nr^2h

n = 22/7

r = radius

903 = 11.5 x r^2 x 3.14

r^2 = 903 / (3.14 x 11.5)

r = 5 cm

diameter = 10cm
