K = 7 since it is literally the same in terms of slope. Its just the constant that changes and therefore it is equal to the units mentioned.
A= l*w
168= 14*w
Divide both sides by 14
168/14= 14w/14
12=w
Final answer: 12 ft (I'm not sure if you meant to switch the order of b and c).
Its B bro becauseiys a negative so you would get rid of the symbol then flip the negative
For 27) D
For 28) A
Hope that helps!
10= -4 + x x=14 because you do the opposite of the sign you see in this case its a plus sign so you subtract -4 from ten and since the 4 is a negative and your subtracting you would add 4 I know this probably didn't help it sounds really confusing but I have hope that it did :)
