An architect is making a deck in the shape below where one unit equals 1 foot if 1/4 of the deck stain can cover 8 square feet how many cords I need purchase to stain the deck once enter your answer in the Box

5 quarts. Split the shape into a rectangle and two triangles on the sides. find the area of the rectangle using length times width (7x4=28) find the area of the triangles using 1/2 times length times width (1/2x4x3=6) add all of them together to get 40. divide 40 by 8 to get how many quarts are needed

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2
