Step-by-step explanation:
(3x^2-2)(3x^2+3)
expand to remove the bracket
9x^4 + 9x^2 -6x^2 - 6

Answer:
{x,y}={ 5/9,0}
Step-by-step explanation:
9x - 2y = 5
y = 0
9x - 2•() = 5
9x = 5
x = 5/9
By now we know this much :
x = 5/9
y = 0
⇒{x,y} = {5/9,0}
Answer:
12+x=12+4=16
3x+y=3*4+7=12+7=19
4y-10=4*7-10=28-10=18
1/2xy=1/2*4*7=28/2=14
