Step-by-step explanation:
8*10=80ft *3= 240 but thats over budget
Answer:
80 m.
Steps: perimeter =4 x side
=4x20=80m
Multiply a by the determinant of the 2×2 matrix that is not in a's row or column.
Likewise for b, and for c.
Sum them up, but remember the minus in front of the b.
6+2/3(3-6x)=x-2 combine like terms
2/3(3-6x)=x-2-6
2/3(3-6x)= x-8 distribute 2/3
2/3(3)- 2/3(6x)=x-8
6/3-12x/3=x-8 divide where you can
2-4x=x-8 combine like terms
2+8=x+4x add
10=5x divided by 5
10/5=5x/5
2=x
