Find all real solutions of the equation, approximating when necessary.
x2 + 4x + 10x+15= 0
a. X8 2.426
c. 78 5.128
b. XX-2.426
d. X8 -5.128

id say b XX-2.426

Step-by-step explanation:

will if u add all the xs toghether depending on what grade ur in it would probly be 16+15=0 but thats not one of the answers so you would have to simplify it or i shoud say solve it differently

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
