Help me please? ASAP. 10 points??
alex41 [277]

Answer:

D) 16x^2 + 4x


Step-by-step explanation:

So a since there is two lengths and two height, you are gonna have to add them all up.

<u>5x^2 + 2x</u> + <u>5x^2 + 2x</u> + <u>3x^2</u> + <u>3x^2</u>

<u>(</u>See why I put the length value and width value twice? Because there is two of each.)

Now start adding up common factors. Let's start with any x^2

10x^2+2x + 2x + 6x^2

I added up the 5x^2 together to get 10x^2 and I added the 3x^2 together to get 6x^2, now you are gonna add those two up

16x^2 + 2x + 2x

(Just from looking at this, you can easily cross out answers A and B)

Now add the x together

16x + 4x

So the the answer is D

Does anyone know the answer to these two problems?
Nady [450]

Answer:

8) -8, -9

9) 4, $ \frac{1}{2} $

Step-by-step explanation:

8) x² + 12x + 27

Solutions of a polynomial means the values of $ x $ such that the polynomial becomes zero. $ i.e., y = 0 $.

We use the following formula to determine the solutions of a quadratic equation of the form: $ ax^2 + bx + c = 0 $

    $ \implies x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} $

In this equation, $ a = 1; b = 12; c = 27 $

Substituting in the formula, we have:

$ x = \frac{-12 \pm \sqrt{144 - 108}}{2} $

$ \implies x = \frac{-12 \pm 6}{2} $

Taking 2 common outside we get:

$ x = - 6 \pm 3 $

Therefore, we get two solutions viz, x = -3, -9.

9) 2x² - 9x + 4 = y

X- intercepts of a polynomial means the value of x such that y = 0. It means the roots of the polynomial.

Solving the equation using the formula above, we get:

$ x = \frac{-(-9) \pm \sqrt{81 - 32}}{2(2)} $

$ \implies x = \frac{9 \pm 7}{4} $

The values of x = 4, $ \frac{1}{2} $.

Hence, the answer.

How are absolute values used to describe quantities ?
Nady [450]

Answer:

Absolute value is a number's distance from 0, so when comparing quantities, such as positive and negative, the greater absolute value is of that number.

For ex:

|-11| > |6| ,  because |-11| = 11, |6| = 6, and 11 > 6.

So, |-11| > |6|
