Kristen recently sold some farmland and bought a new plot that consists of 3,151 acres. Kristen calculates that this is 15% more acreage than she used to own. What was the
acreage of the old land?

1. a right triangle is graphed on a coordinate plane. find the length of the hypotenuse. round your answer to the nearest tenth. 2. use the angle relationship in the figure below to solve for the value of x. assume that lines a and b are parallel and line c is a transversal.

Complete the solution of the equation. find the value of y when x equals to 28 x+3y=28

Ireally need subtract and simplify.(-y^2 – 4y - 8) – (-4y^2 – 6y + 3)show your work, ! i will mark you brainliest but you have to show your work.
