The second in the top row is this:
42.4-1.5(TIMES)3.1
42.4-46.5
-4.1
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.
The median means the number that is in the middle of the spnumber sequence in least to greatest.
1) number the numbers up. 2,2,3,6,7
2) start by crossing off the last from the greatest. Then you can see that 3 is the median.
