X would be less than or equal to 6 since 58-4 is 54 and that’s equal to 9x so divide by 9, equaling 6. X would be more than 30 since 3+2 is 5 and multiplied by 6 is 30

9x + 4 ≤ 58

=> 9x ≤ 58 - 4

=> 9x ≤ 54

=> x ≤ 54/9

=> x ≤ 6
______________

1/6x − 2 > 3

=> 1/6x > 3 + 2

=> 1/6x > 5

=> x > 5×6

=> x > 30

Coefficient of x^2 in expansion of the binomial theorem (2x-1)^4 show your work
tekilochka [14]

Answer:

24

Step-by-step explanation:

If you use Pascal's triangle, which I did, you will look at the 5th row of the triangle which contains the numbers 1, 4, 6, 4, 1

If we expand using a = 2x and b = -1, then the expansion looks like this:

1(2x)^4(-1)^0+4(2x)^3(-1)^1+6(2x)^2(-1)^2+4(2x)^1(-1)^3+1(2x)^0(-1)^4

If you simplify all that down by multiplying, you'll get

16x^4-32x^3+24x^2-8x+1

If you don't know how to use Pascal's triangle, you need to learn.  It's so very cool!

Find the factors and zeros of 6x^2 +8x-28=2x^2 + 4
Mice21 [21]

Answer:

First solve the equation:

6x^2 + 8x -28 = 2x^2 + 4

=> 6x^2 - 2x^2 + 8x - 28 -4 = 0 => 4x^2 + 8x - 32 = 0

Extract common factor 4:

=> 4[x^2 + 2x - 8] = 0

Now factor the polynomial:

4(x + 4) (x - 2) = 0

=> the solutions are x + 4 = 0 => x = -4, and x - 2 = 0 => x = 2.

So the answer is the option B: 4(x + 4)(x - 2); {-4, 2}

HOPE THIS HELPS! :D
