![2551\dfrac{1}{2}](https://tex.z-dn.net/?f=2551%5Cdfrac%7B1%7D%7B2%7D)
Step-by-step explanation:
![\bf l = 20\dfrac{\sf 1}{4} \ in = \dfrac{81}{4} \ in](https://tex.z-dn.net/?f=%5Cbf%20l%20%3D%2020%5Cdfrac%7B%5Csf%201%7D%7B4%7D%20%5C%20in%20%3D%20%5Cdfrac%7B81%7D%7B4%7D%20%5C%20in)
![\bf w = 10\dfrac{1}{2} = \dfrac{21}{2} \ in\\\\\\h = 12 \ in](https://tex.z-dn.net/?f=%5Cbf%20w%20%3D%2010%5Cdfrac%7B1%7D%7B2%7D%20%3D%20%5Cdfrac%7B21%7D%7B2%7D%20%5C%20in%5C%5C%5C%5C%5C%5Ch%20%3D%2012%20%5C%20in)
Volume of rectangular prism = l*w*h
![= \dfrac{81}{4}*\dfrac{21}{2}*12\\\\\\= 81 *\dfrac{21}{2}*3\\\\\\= \dfrac{5103}{2}\\\\\\= 2551 \dfrac{1}{2} \ cubic \ inches](https://tex.z-dn.net/?f=%3D%20%5Cdfrac%7B81%7D%7B4%7D%2A%5Cdfrac%7B21%7D%7B2%7D%2A12%5C%5C%5C%5C%5C%5C%3D%2081%20%2A%5Cdfrac%7B21%7D%7B2%7D%2A3%5C%5C%5C%5C%5C%5C%3D%20%5Cdfrac%7B5103%7D%7B2%7D%5C%5C%5C%5C%5C%5C%3D%202551%20%5Cdfrac%7B1%7D%7B2%7D%20%5C%20cubic%20%5C%20inches)
Answer:
A
Step-by-step explanation:
DE corrsponding to the LN, EF corrsponding to the MN, and LN:DE=MN:FE=3
and angel N is corrsponding to the angle E,so it 's SAS.
1.) r=-1/3
2.) x=-33/29
3.) x=-4/5 x=2/5
((4^7)/(5^2))^3 I'm pretty sure this is how you would right the problem to begin with
