Take half of the middle coefficient.
Then square it.
-12/2 = -6
(-6)^2 = 36
c = 36
Answer:
90
Step-by-step explanation:
600(.15) = 90
Y=4x+4
I think this is it u just have to simplify to get it to y=mx+b
she had 98 but spent 10.85 so she now has:
98-10.85 = 87.15
skateboard cost 64
87.15 -64 = 23.15 is what she can spend on cookies
23.15 / 1.65 = 14.03 she can't buy more than 14 cookies
so answer is c. n ≤ 14
