Ally the turtle was born with 1 square on her shell, as in the first picture below. When she was 1 year old, 8 new squares appeared around the old squares, as in the second picture below. Each year, a new group of
squares appeared around the old squares.
How many new squares appeared on Ally's shell each year? Extend the pattern and fill in the blanks in the
chart below.

Simply 8x squared + 5(7x squared- x) - 2x =

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?

Find the zeros of each function. f(x) = x^2 + 5x - 6
