Answer:
yes
Step-by-step explanation:
Tan30=9/x so it will be 9((3)^1/2)
Answer:
1) a) yes
b) no
c) a² - 39
(a)² - (sqrt(39))²
(a - sqrt(39))(a + sqrt(39))
This quadratic can be split into real factors, but not rational
sqrt(39) is a real number, but not rational
After distributing you get this equation. 2r+4 =2r+4 since it's the same expression on both sides the answer would be r=All real numbers because no matter whatever real number u put for r it will come out the same on both sides
