Find the sum of -822 + 3 and -92? + 3x – 3.

Find the values of y: 3y^3(y^2+ 2/3y)=0

Kayla wants to find the width, ab, of a river. she walks along the edge of the river 65 ft and marks point c. then she walks 25 ft further and marks point d. she turns 90° and walks until her location, point a, and point c are collinear. she marks point e at this location, as shown. (a) can kayla conclude that δ and δ are similar? why or why not? (b) suppose de = 15 ft. what can kayla conclude about the width of the river?

Which number line represents the solution set for the inequality - x 24?
