Answer:
Step-by-step explanation:
(D+R) = 80:2 = 40
D = 40-R
(D+8) * R = 72X
Thay D=40-R
(40-R+8)*R = 72X
R=1.55, D=38.45
Answer: What does the page say?
Step-by-step explanation:
<h2>
THE ANSWER IS D. 5</h2>
my answer is too short so just ignore this part but I can promise the answer is five.
We need to cancel out the discontinuity in x = 4
In order to do that, factorize the numerator:
5x⁴ - 20x³ = 5x³(x-4)
This way, your function will be:
f(x) = <span>5x³(x-4) / (x-4)
and the two parentheses cancel out, leaving
</span>f(x) = <span>5x³
</span>
which at x = 4 gives:
f(4) = <span>5·4³</span> = 5 · 64 = 320
Therefore K = 320.
Answer:

Step-by-step explanation:
Given that,

We need to find the value of f(x)-g(x).
Put the values of f(x) and g(x). So,

So, the value of f(x)-g(x) is equal to
.
