(3x + 2) (2x - 5) = ax² + kx + n .
What is the value of a - n + k ?

Answers

Answer 1

Answer: $(3x + 2) (2x - 5)=ax^2+kx+n \n \n =3x\cdot 2x - 3x\cdot 5 +2\cdot 2x - 2\cdot 5=\n \n=6x^2-15x+4x-10=\n \n=6x^2-11x-10\n \n a=6, \ n=-10 , \ k=-11 \n \na - n + k = 6-(-10)+(-11)=6+10-11= 5$

-2n-h(4rx-6s)-3rx+3s i need help doing this problem

Answers

Ok, first step is to distribute the h to get rid of parenthesis:

-2n - 4hrx + 6hs -3rx +3s

Then you would combine like terms, but there are none! So that's your answer.

- 2n - h(4rx - 6s) - 3rx + 3s =

= - 2n - h×4rx - h×(- 6s) - 3rx + 3s

= - 2n - 4hrx + 6hs - 3rx + 3s

= 2(3hs - 2hrx - 2) - 3(rx - s)

(4x3 + 3x2 - 30x - 10) ÷ (x -3)

Answers

The division of (4x³ + 3x² - 30x - 10) by (x - 3) is equal to 4x² + 3x - 21 with a remainder of -73.

How to divide the polynomial

To divide the polynomial (4x³ + 3x² - 30x - 10) by (x - 3), we can use long division Divide the first term of the dividend by the first term of the divisor:

4x³ / x = 4x²

4x² * (x - 3) = 4x³ - 12x²

(4x³ + 3x² - 30x - 10) - (4x³ - 12x²) = 3x²- 30x - 10

Bring down the next term from the dividend:

3x² - 30x - 10

3x² / x = 3x

Multiply the divisor (x - 3) by the result from step 5:

3x * (x - 3) = 3x² - 9x

(3x² - 30x - 10) - (3x²- 9x) = -21x - 10

Bring down the next term from the dividend:

-21x - 10

-21x / x = -21

Multiply the dvisor (x - 3) by the result from step 6:

-21 * (x - 3) = -21x + 63

(-21x - 10) - (-21x + 63) = -73

The result of the division is the sum of the quotients obtained in each step:

4x² + 3x + (-21)

Answer:

10 mil

Step-by-step explanation: 10x10x10x10x10x10x10= 10,000,000

If the number is expressed in words, first write it down as an ordinary decimal number and then convert. Thus, "ten million" becomes 10,000,000. There are seven zeros, so in powers of ten notation ten million is written 10^7
