I hope this picture helps, but next time try to chose a number to cancel out the fraction. Example, y=1/3x+4 chose 3,6,9 and other multiples of 3.
The answer is -6x^2 + 7x, or answer choice A.
7 is the answer because 7 is great and is always the answer
I don’t see the image can you please add one to the comments so I can answer it. Thanks
Me. Pennington had 6 inches left over.
Explanation.
2 1/4 feet is equal to 27 inches. If he used 21 inches, then he'd had 6 inches left over; 27-21=6.
Have a good day!
