Answer:
f(4)=26
Step-by-step explanation:
f(2)=16
F(x) = kx+6
16=k(2)+6
16-6=k(2)
10=k(2)
<u>10</u> =<u>k(</u><u>2</u><u>)</u>
2 2
5= k
f(4)=k(4)+6
=5(4)+6
=20+6
f(4)=26
Answer:
12.9
Step-by-step explanation:
cos 72 = 4/x
x = 4/cos72
x = 12.9
Any with an odd number of minus signs.
Perhaps the 1st and 4th, if I read it right.
What you need to do is find the smallest multiple that they both have (i forgot what that is called) list them like this:
12: 24 36 48 60 72
15: 30 45 60 75
60 is the lowest number that they both can multiply to
60 cups/lids is the answer
