jack bought a tree to plant in his front yard. the tree grows at an approximate rate of 9 inches per year. after 4 years, the tree is 5 feet tall. write an equation in slope-intercept form to find the height (in feet) of the tree, y, after x years. then, find the number of years it will take the tree to reach 20 feet

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.

step-by-step explanation:

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
