Answer:
I would round to 3, so the length of the sidewalk would be about 8 x 3 = 24 feet.
Step-by-step explanation:
is closer to 3 and if you convert it to decimal which will be 2.83 with a bar on top of 3, it's still close to 3.
Hope it will help you..............
1) 2x + 3 = 2x + 3
This works because if you solve it, you will get either x = x or 3 = 3 which are always true, so x, can have an infinite number of solutions
2) 3(x + 4) = 3x + 11
This has no solution because if you solve it, you're gonna get 12 = 11 and that is NEVER true. Whatever x is, 11 cannot equal 12!
