Answer:
2x + 3(8 - 3x) = 3
x = 3
y = -1
Step-by-step explanation:
2x + 3y = 3
y = 8 – 3x
2x + 3(8 - 3x) = 3
2x + 24 - 9x = 3
7x = 21
x = 3
y = 8 - 3(3)
y = -1
Answer: Come on, don’t people learn these things in school!
Step-by-step explanation:
The simplified form of this polynomial is (n(20n + 1))/5
Answer Perimeter = 33in
Step-by-step explanation:
AC = 20
BD = 20
AB = 13
O is the midpoint
OD = OC = 20/2 = 10
AB = DC = 13 in
P = DC + OD + OC = 13+10+10 = 33in
