b] 5√ 6 and 6√ 5
c] 7√ 3 and 9√ 3
d] 9√ 2 and -9√ 3

Answers

Answer 1

Answer:

The pair which have the same radicals is the pair of like radicals which are 7√ 3 and 9√ 3 therefore, option (C) will be correct.

What is a number system?

The number system is a way to represent or express numbers.

Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.

Given four radicals pair are,

2√ 3 and 2√ 5

5√ 6 and 6√ 5

7√ 3 and 9√ 3

9√ 2 and -9√ 3

The only pair which have the same radical value (√ 3) is 7√ 3 and 9√ 3

Hence "The pair which have the same radicals is the pair of like radicals which are 7√ 3 and 9√ 3".

Find the value of x and RT if RS=24 cm

Answers

RS = RT + TS = 24 cm

Let's plug our values into the equation above

24cm = 6x - 4 + 10cm

Combine like terms

24 cm = 6x + 6 cm

Subtract 6 cm from both sides

18 cm = 6x

Divide both sides by 6

3 = x

Plug 3 into the expression for RT

RT = 6(3) - 4 = 18 - 4 = 14 cm

Similarly, we know that TS = 10 cm and RS = 24 cm

24 cm - 10 cm = 14 cm

RT = 14 cm

14 cm = 6x - 4

Add 4 to both sides

18 cm = 6x

Divide both sides by 6

3 = x

Which are zeros of the following polynomial? 6x 2 - 11x - 10 = 0

Answers

Hello,

0=6x²-11x-10=6x²-15x+4x-10=3x(2x-5)+2(2x-5)=(2x-5)(3x+2)

Zeroes are: x=5/2 and x=-2/3

Answer:

The zeros of the given polynomial $6x^2-11x-10=0$ are $(5)/(2)$ and $(-2)/(3)$ .

Step-by-step explanation:

Consider the given polynomial,

$6x^2-11x-10=0$

We have to find the zeros of the given quadratic equation,

Solving using middle term splitting method,

-11x can be written as a sum of -15x and 4x and it will given product as -60.

The equation thus can be written as,

$6x^2-11x-10=0$

$\Rightarrow 6x^2+4x-15x-10=0$

$\Rightarrow 2x(3x+2)-5(3x+2)=0$

$\Rightarrow (2x-5)(3x+2)=0$

$\Rightarrow x=(5)/(2)$ and $\Rightarrow x=(-2)/(3)$

Zeros satisfies the polynomial , when we put them back in the equation, it must give result as zero.

Thus, the zeros of the given polynomial $6x^2-11x-10=0$ are $(5)/(2)$ and $(-2)/(3)$

36x^2-21x-30 factor

Answers

Easy...

to even begin to factor..you must factor out a 3, to simplify your answer.

3(12 $x^(2)$ -7x-10)

Now, you can factor.

$3(12 x^(2) -7x-10)$

So..to find the answer...

12*-10=-120x
and
you would use -7x

What multiplies to -120..but adds to -7?

-15*8=-120
and
-15+8=-7

To find the answer, plug in what you know..

3(3x+2)(4x-5)

Thus, your answer.
