Answer:

for the first one,

I would prolly distribute the number on the outside of the parenthesis into the first pair of parenthesis but keep the parenthesis there, so for #17 it would turn out to be (2x-2)(x+2),

and then use foil (first outer inner last). so then #17 is 2x^2 + 4x - 2x - 4

and then you'd combine like terms to get the answer: <u>2x^2 + 2x -4</u>

<u />

Step-by-step explanation:

hope this helped a little bit :))

You have to used distributive property

i am not doing all of your questions for you but i will do a bit of the first one to try to help and give an example

11. (x+1)^2 + (x+2)^2
x^2+1^2 + x^2+2^2
then combine like terms and find the answers

idk if this is correct but I hope so and I hope this helps (please mark brainliest <3)

Solve for x: −2x + 5 &lt; 7 <br> Please Help Meh!! DO you LIKE to see people STRUGGLE?!?!
Arlecino [84]

x > -1


-2x+5 < 7

-2x<2

Now since you divide by (-1) to get positive 2,you need to flip the sign

(-2)/(-1)= 2     2/(-1)=-2

SO

2x>-2

x > -1

To check  the solution do not replace the x by -1 because it shouls be more than -1  (You can choose 0,1,2,3....)

Example  choose x=3

-2x3+5<7

-6+5<7

-1<7

Standard deviation measures _____ risk while beta measures _____ risk.
Stolb23 [73]

Answer:

Standard deviation measures Total risk while beta measures Systematic risk.

Step-by-step explanation:

The total risk is the total variability of the portfolio and includes the systematic risk and the unique risk.

The systematic risk is measured by the beta coefficient and it considers the no diversified risk such as changes in the global market. Unique risks are the ones that result from factors specifically related to the company.
