What is the value of z so that -9 and 9 are both solutions of x^2+z=103?

Z = 22

Step-by-step explanation:

plug 9 into the equation

9^2 + z = 103

81 + z = 103

subtract 81 from both sides

z = 22

do the same with -9

since you are squaring -9 this still equals 81 so the answer is the same.

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

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.
