On a large sheet of graphing paper, Joan has drawn a picture of a castle by connecting vertex points on the grid. She decides that the picture would look better if it were reversed, changing the left side for the right side and the right side for the left. The vertex point that marks the top of the castle's flagpole is at (122, 73). If she reflected the picture across the y-axis, then what would be the new coordinates for the top of the flagpole?

A rectangular poster has an area of 22 square feet. It is 3 and two thirds feet wide at its base. What is the height of the​ poster?

Answers

A=area=22
sq ft; L=length;
W=width=3 2/3 ft
3 2/3 ft=11/3 ft
A=L*WA/W=L
22sq ft/(11/3)ft=L
6ft=L
So the length (height) of the poster is 6 feet.
the height of the poster is 66 feet

S squared - 16s - 57

Answers

s² - 16s - 57 = s² - 16s + 64 - 121 = s² - 2*1*8 + 8² - (11)² =
we use the formula  a² - 2ab + b² = (a-b)²
(s - 8)² - (11)²
we use the formula a² - b² = (a+b)*(a-b)
(s - 8 )² - (11)²
   a²      -   b²
 
[ (S - 8) - 11] * [ (S-8) + 11] = [S-19] * [S+3]
