Answer:
with what?
Step-by-step explanation:
Given that z is directly proportional to x, then:
zαx
hence;
z=kx
therefore:
k=z/x
when x=3,z=54
thus;
k=54/3
=18
hence;
z=18x
therefore the value of z when x=12 will be:
z=18*12
z=216
The answer is z=216
Perpendicular angles are where 2 lines form 90 degree angles, such as in C
5*9=45
3*9=27
45-27=8
9*2=18
Therfeore the answer is A.
The answer would be 7.04^3
