a triangular lot in a park has a base with a measure that is 4 more than twice the height of the lot. the area of the lot is 99 square feet. since the area of a triangle is found by using the formula a=1/2 bh, the area for this lot can be represented by the equation 99=1/2(2h+4)h, where h represents the height of the triangle.
what is the height of the lot?

Simplify the equation they gave you: 99 = 1/2*(2h + 4)*h; first multiply

99 = (h + 2)*h

99 = h² + 2h; subtract h² + 2h from both sides

99 - h² - 2h = 0; rearrange

-h² - 2h + 99 = 0; factor

(-h + 9)(h + 11) = 0; set each factor equal to 0

-h + 9 = 0 → h = 9           h + 11 = 0 → h = -11

The value of h has to be positive so lets go with 9. Plug it ito the equation to make sure.

99 = 1/2*(2(9) + 4)*9

99 = 1/2*22*9

99 = 99; that means that the answer was right → 9 is the height

I hope this helps you!

Step-by-step explanation:

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.
