Answer:
14vr
Step-by-step explanation:
7vr - (-7rv)=
Subtracting a negative is like adding
7vr + (7rv)=
Changing the order of rv to vr
7vr + (7vr)=
Combing like terms
14vr

Figure on the right is simply figure on the left but flipped on its side. we know this because the question tells us the shapes are congruent (which means equal, the same)
Answer:
50% of 3000
Step-by-step explanation:
49% is very close to 50% (half). 3,025 pounds is very close to 3,000 pounds.
Half of 3,000 pounds is 1,500 pounds.
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
