Answer:
<h2>
</h2>
Step-by-step explanation:
To solve for h multiply through by 3 to eliminate the fraction
That's
Divide both sides by πr² to make h stand alone
We have the final answer as

SOH CAH TOA tells you
... cos(B) = a/c
... 4/5 = 8/c
... c = 10 . . . . . multiply by 5c/4
By the Pythagorean theorem,
... b = √c² -a²) = √(10² -8²) = √36 = 6
The lengths of the other two sides are: b = 6, c = 10.

You can tell from the value of the cosine that this is a 3-4-5 right triangle. You can tell from the value of "a" that the scale factor is 2. That means the other two sides are 6 and 10.

Answer:
L = 3x - 2
P = 6x - 10
Step-by-step explanation:
Area = length * width
A = l*w
so if the width is 6 inches we can say w = 6
and we can say that l = to the length of the rectangle
if we substitute this:
(18x - 12) = l * 6
we get the answer l = 3x - 2 since we divide both sides by 6.
the expression for length of the rectangle is -> l = 3x - 2
for the perimeter:
P = 2(l + w)
if we substitute this:
P = 2(3x - 2) + 6
distributive property:
P = 2(3x) - 2(2) + 6
then would be:
P = 6x - 4 + 6
(combine like terms) -> P = 6x - (4 + 6)
then you would get: P = 6x - 10
which can also be writtern as -> P = 6x + (-10)
but this is not simplified so you would just write it as 6x - 10
