If z varies inversely as w^2, and z=10 when w=6, find z when w=2

90

Step-by-step explanation:

If z varies inversely as w^2 then:

z=k/(w^2)  

z=10 when w=6:

10=k/36---> k=360

z=k/2^2

z=360/4=90

the answer is: the length is 5/6 yards.

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
