its 14n+21. 7×2n is 14n, and 3×7 is 21
Let's solve the equation:
9x+27 = 9(x+2)+9 ← Distribute 9 to the x and 2
9x+27 = 9x+18+9 ← Combine like terms
9x+27 = 9x + 27 ← Subtract 27 from both sides
9x = 9x
Infinitely many solutions would be correct because no matter what x is, it will always equal each other the both sides of the equation because it is 9 times x on both sides.
Answer:
smaller pieces must be larger than 3 feet
Step-by-step explanation:
x is the longer piece
x>32
x-20>12
