Answer:
0.8r
Step-by-step explanation:
r - 0.2r
= 1r - 0.2r ← factor out r from each term
= r(1 - 0.2)
= r × 0.8
= 0.8r
Step-by-step explanation:
answer is in photo above
you multiply -10 and nine and you get -90 hope this helps.
Step-by-step explanation:
By definition we have that the volume is given by
V = h * w * l
where
V: Volume
h: height
w: width
l: length
Clearing the height we have:
h = V / (w * l)
h = (5 - x) / ((x) * (x - 2))
The expression is not defined for the values of x that make the denominator zero:
((x) * (x - 2)) = 0
x = 0
x = 2
Answer
h = (5 - x) / ((x) * (x - 2))
x = 0
x = 2
