Answer:
3 inches
Step-by-step explanation:
(14+2x) × (15+2x) = 2(14×15)
210 +30x +28x + 4x² = 420
4x² + 58x - 210 = 0
2x² + 29x - 105 = 0
2x² + 35x - 6x - 105 = 0
x(2x + 35) - 3(2x + 35) = 0
(x - 3)(2x + 35) = 0
x = 3, -35/2(not possible)
This is very simple, all you have to do is subtract 18 and 6 and that would be 12, and now we have 12 as a POSSIBLE answer, lets check our work to be 100% correct so now try to add 12 and 6 and we get 18, so yay it made the equation true and since its true its right so that's the answer.
Answer: c = 12 so 18 = 12 + 6 is true.
Answer:
x>5 so any number greater than 5 will work
Step-by-step explanation:
6x-8>22
move -8 to the other side so addition cuz it's a negative number
6x>30
now divide the 6x by 6 and 30
so now it will be
x>5
The answer is 16 hours. This is because 5/8 is equivalent to .625 so we divide the total capacity by that increment and we get 16.
