The perfect squares on either side of 21 are 16 and 25 of which the roots are:
4 and 5
3w = $9.25 would be the equation in this case. In order to solve it, you must divide $9.25 by 3. $9.25 / 3 = $3.83 (repeating bar over the second 3). The cost of one box of popcorn is $3.83.
3 (2x + 1) = 21
6x + 3= 21
-3 -3
6x = 18
Divide each side by 6, and x equals 3.
3 (2(3) + 1) = 21
3 (6 + 1) = 21
18 + 3 = 21
Hope this helps! Can I please have brainliest so I can level up? Thank you!
It's like saying 6(x+4)=x-11.
