The solutions to which of the following equations are 4 and 10?

Equation B.

Step-by-step explanation:

These are all quadratic equations, which are solved through the quadratic formula:

where a is the coefficient of our second degree term (the number that is multiplying ), b is the coefficient of our first degree term (the number multiplying ), and c is our independent term (the number that is not accompanied by any ).

Quadratic equations can have either one, two or zero solutions. To find hem, we simply plug the coefficients into the formula (For example: in our first equation, , , ).

Repeating this process in all four equations, we get that there is only one equation that meets our conditions:

Equation B. Solutions: and

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.
