When completing the square <span>x=9.12311 and </span><span>x=<span>0.876894</span></span>
If r(x)= 11x, and c(x)=6x +20, then just put that into the equation.
So instead of p(x) = r(x) - c(x)
I would be p(x) = 11x - 6x + 20
Now solve.
p(x) = 5x + 20 is your final answer, so A.
It seems that you are trying to find the length of hair of Florencia on Tuesday.
Given that length of the hair of Florencia on Monday = h centimeters
On Tuesday, she got hair cut.
So new length of the hair of Florencia on Tuesday = 75% of Monday value
= 75% of (h)
= 0.75* (h)
= 0.75h
Hence final answer is the length of the hair of Florencia on Tuesday is ( 0.75h ) centimeters.
Step-by-step explanation:
V = h × w × l
7650 = 9 × 25 × l
So,
l = 7650 ÷ 9 ÷ 25
l = 850 ÷ 25
l = 34
For the final, the length is 34.
