Sub x=3 into ((x^2)-x)^2 - (x^2 - x) = 30. So the answer is A.
Answer:
width=16
length=38
Step-by-step explanation:
perimeter of a rectangle=2(length+width)
108/2=length+ width
54=length+ width
54-width=length
also:
length-6= 2×width
length=2width +6
now you can put the length we found, in the second equation:
54-width=2width+6
54-6=2width+width
48=3width
width=16
now do the exact same thing with one of the equations we created in the beginning.
either this:
54-width=length
or this:
length=2width +6
as the 1st one is simpler, I use that:
54-(16)=length
length=38
Answer:
8
Step-by-step explanation:
y = 2
z = 8
8y - z
= 8 ( 2 ) - 8
= 16 - 8
= 8
