Answer:
3 (8v+5) (8v-5)
Step-by-step explanation:
192v^2 -75
factor out a 3
3 (64v^2 -25)
now the inside is a difference of squares)
a^2 – b^2 = (a + b)(a – b) where a = 8v and b =5
3 (8v+5) (8v-5)

Answer:
X = -29/10
Step-by-step explanation:
City hall to post office = 6 1/2 miles = represented by f
city hall to library site = 1 1/4 miles = represented by d
library site to post office = unknown. = represented by e
City hall to library site PLUS library site to post office IS EQUAL to city hall to post office
d + e = f
1 1/4 + e = 6 1/2
find e.
e = 6 1/2 - 1 1/4
e = 13/2 - 5/4
e = (13*2)/(2*2) - 5/4
e= 26/4 - 5/4
e = (26-5)/4
e = 21/4
e = 5 1/4 distance from library site to post office.
To check:
d + e = f
1 1/4 + e = 6 1/2
1 1/4 + 5 1/4 = 6 1/2
6 2/4 = 6 1/2
6 1/2 = 6 1/2
