We want to find the zeros of this polynomial:
fredd [130]

Answer:

x = -3 and x = -3/2

Step-by-step explanation:

After writing down the polynomial, split it; put a line between 3x^2 and -18x. Look and 2x^3 + 3x^2 and -18x - 27 separately and factor them both:

p(x) = 2x^3 + 3x^2 <u>- 18x -27</u>

p(x) = x^2(2x+3) <u>-9(2x+3)</u>

Now notice how x^2 and -9 have the same factor (2x+3). That means x^2 and -9 can go together:

p(x) = (x^2 - 9)(2x+3)

Factor it once more because there's a difference of squares:

p(x) = (x+3)(x-3)(2x+3)

Now just plug in whatever makes the each bracket equal 0:

x = -3, x = 3, and x = -3/2

Those are your zeros.

A) if x=4 evaluate the perimeter of the blanket. Don’t forget to include the measurement in your final answer.
Tanzania [10]
Formula for perimeter of a rectangle:  P = 2W + 2L

Here, P = 2(x-3 ) cm + 2(3x+7) cm = 2x - 6 + 6x + 14   (cm)

Combine like terms:  8x + 8   cm (simplest form)  This is the perimeter.

Now let x = 4:  P(x=4) = 8(4) + 8   cm   = 40 cm

30 is 60%of what number?
Rom4ik [11]

Answer: 50


Step-by-step explanation:


Step 1: 60% = .60

Step 2: 30 = .60Y

Step 3: Divide both sides of the equation by .30 to isolate the variable Y.

30/.60 = .60/.60Y

50=Y

Therefore, 30 is 60% of 50.
