Use PEMDAS:
[(30+6) -3^2] / 9* 2
= (36 -9)/ 9* 2
= 27/9* 2
= 3*2
= 6

Answer:
Step-by-step explanation:
x^2 + 4x = 15.....take half of ur x term, then square it, then add to both sides
x^2 + 4x + 4 = 15 + 4
(x + 2)^2 = 19
sqrt (x + 2)^2 = sqrt 19
x + 2 = sqrt 19
x = -2 (+ - ) sqrt 19
so x = -2 + sqrt 19 or x = -2 - sqrt 19
Solving equations simple
4n + 3 =11
