Answer:
A+6+A = 20
A = 7
Step-by-step explanation:
J = number of problems Juana completed
A = number of problems Andy completed
J+A=20
J = A + 6
Replace J with A+6 in the first equation
A+6+A = 20
2A +6 = 20
Subtract 6 from each side
2A +6-6 = 20-6
2A =14
Divide by 2
2A/2 = 14/2
A = 7
=3*2+bx-6
= 6+bx -6
= 6-6+bx
=0+ bx
B=x
124 square units
you just have to count the top, bottom, and a side and times by 2
