Answer:

B. It could be 6th degree polynomial with a Negative leading coefficient.

Step-by-step explanation:

Since       (20)        =        (-3)                     [we can cross multiply]

            (x²- 25)                (5-x)

⇒                     (20)(5 - x) = (-3)(x² - 25)       [expand the brackets]

⇒                     100 - 20x = -3x² + 75          [make the equation equal to zero]

⇒             3x² - 20x + 25 = 0                      [expand the middle term using

                                                                     appropriate factors of the product

                                                                     of the terms a and c (3 × 25)]

⇒       3x² - 15x - 5x + 25 = 0                      [factorize the terms]

⇒            (3x -  5 ) (x - 5)  = 0                      [using the knowledge that for the

                                                                       produc to be 0, one of terms

                                                                       must be zero]

⇒            (3x -  5 ) = 0     OR   (x - 5)  = 0     [solve for x in each case]

⇒                       x = ⁵/₃    OR           x = 5

1) Simplify √108 to 6√3

6√3 - 12/√3

2) Rationalize the denominator: 12/√3 · √3/√3 =12√3/3

6√3-12√3/3

3) Simplify

6√3/3

Answer:  -1

Step-by-step explanation:

The rate of change = slope = -1

This is because the rate of change of a linear function is the slope.

Find the value of y:

Answer:

x=-10

Step-by-step explanation:

2x +9= x-1

2x-x=-9-1

x=-10

no because

4986

881

4 1 0 5

there is no regrouping because every top number is equal to or larger than the bottom number

There is no need to regroup to subtract 881 from 4,986, the answer would be 4105.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

It is given that:

The two numbers are:

881 and 4986

As we know,

The term PEDMAS describes the sequence in which arithmetic operations must be carried out in an equation.

According to this rule, operations should be carried out in the following order: parentheses, exponents, multiplication or division, then addition or subtraction.

After applying the concept of arithmetic operation:

= 4986 - 881

= 4105

Thus, there is no need to regroup to subtract 881 from 4,986, the answer would be 4105.

Answer:

Hence, the value of x is 1/39.

Step-by-step explanation:

[tex]\sf \leadsto \dfrac{3x + 1}{x - 2} = \dfrac{-6}{11}[/tex]

[tex]\sf \leadsto 11(3x + 1) = -6(x - 2)[/tex]

[tex]\sf \leadsto 33x + 11 = -6x + 12[/tex]

[tex]\sf \leadsto 33x + 6x = 12 - 11[/tex]

Answer:

(7x+3)+(-x-5)=-16

or,7x+3-x-5=-16

or,6x-2=-16

or,6x=-16+2

or,6x=-14

or,x=-14/6

hence x=-14/6

Answer:

17/3 should be subtracted from both the numerator and denominator to obtain a fraction equal to 1/4.

Step-by-step explanation:

Let the number be x

5-x /3-x= 1/4

20-4x= 3-x

20-3= 4x-x

X= 17/3

Answer:

u=233

Step-by-step explanation:

281-48=u

233 =u

sorry if i am wrong.

Step-by-step explanation:

281=48-u

281-48=48-u-48 ( substracting 48 on both sides )

233=-u

233×(-1)=-u(-1). (multiplying -1 on both sides)

-233=u.

Answer:

brittleness is weak and breaks easily and is little to no strength, strength means strong and mighty and is tough, very durable

Step-by-step explanation:

I know the definitions

Answer:

Step-by-step explanation:

1 × 4 = 4

4 × 4 = 16

16 × 4 = 64

64 × 4 = 256

256 × 4 = 1024

1024 × 4 = 4096

4096 × 4 = 16384

16384 × 4 = 65536

65536 × 4 = 262144

so the sum of the first 10 term = 1 + 4 + 16 + 64 + 256 + 1024 + 4096 + 16384 + 65536 + 2622144 = 349525
