A=4-3b
subtract 4 from both sides
a-4=-3b
divide by -3 for both sides
(a-4)/-3 = b
let's suppose x is the shortest leg of the triangle
The perimeter of the flower bed is 3x+8 ft
the surface to be coverd by sod would be x×(x+7)/2 sqft
(x+8)(x+8)=(x+7)^2+x^2
x'2+16x+64=x'2+14x+49+x^2
x^2-2x=15
x×(x-2)=15
x=5
(15+8)×$4.23=$97.29 for fencing
32.5sqft×$12.72=$413.4 for the sod
Answer:$2
Step-by-step explanation:Express as two equations . Lex x Be chocolate and y be cookies.
