Answer: b^3+ 64b^2 - b/16 -4
Step-by-step explanation:
The two traingles, VSU and TSR are similar by SAS similarity criteria.
According to the diagram,
UT = TS
and
VR = SR

Similarly for all sides the ratio must be same.
Applying this on the side required here,

Therefore p = 12 units= UV .
"The quotient of a number and 3 less than twice the number" would translate to the expression x/(2x-3)
Basically we have x up top the fraction and 2x-3 in the bottom denominator of the fraction. The slash / means divide
Once... Ocho is 8 and tres is 3
First you bring the 9 over with the seven
![-2= \sqrt[3]{x+9}](https://tex.z-dn.net/?f=-2%3D%20%5Csqrt%5B3%5D%7Bx%2B9%7D%20)
Now cube both sides

Finally subtract 9 over and get

Check
![7=9+ \sqrt[3]{-17+9}](https://tex.z-dn.net/?f=7%3D9%2B%20%5Csqrt%5B3%5D%7B-17%2B9%7D%20)
![7=9+ \sqrt[3]{-8}](https://tex.z-dn.net/?f=7%3D9%2B%20%5Csqrt%5B3%5D%7B-8%7D%20)

7=7
