In order from left to right the answers are -6x 4x -42
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

Answer:
8) -8, -9
9) 4, 
Step-by-step explanation:
8) x² + 12x + 27
Solutions of a polynomial means the values of 
such that the polynomial becomes zero. 
.
We use the following formula to determine the solutions of a quadratic equation of the form: 
In this equation, 
Substituting in the formula, we have:
Taking 2 common outside we get:
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:
The values of x = 4, .
Hence, the answer.
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|
