It 7ft because, 504 divided by 9=56 and then divide it by 8 and you get 7
Answer: c
Step-by-step explanation:
An equation to have no solution means that the system of equations do not intersect at all and therefore will not have any solutions. If an equation has indefinite many solutions then the system of equations will have the same line since they are intersecting each other
If b is the base then the height h=b+6. As we have S=bh/2 then
36=b(b+6)/2;
b²+6b-72=0;
D/4=3²+72=81
b₁=-3-9=-12
b₂=-3+9=6.
The base is always positive so b=6, h=6+6=12.
Answer: base=6 ft, height=12 ft.
