hope this helps :)
Step-by-step explanation:
x1+x2 = (-1-√2)/3 + (-1+√2)/3
= -2/3
(x1) (x2) = (-1-√2)/3 × (-1+√2)/3
= -1/9
the equation :
x² -(-2/3)x + (-1/9) = 0
x² + ⅔ x - 1/9 = 0
Answer:
so basically this is easy if you break it down
Step-by-step explanation:
the triangle area= 5x4/2= 20/2= 10
there are 4 triangles so 10 x 4=40
square area= 5x5= 25
40+25= 65units^2
Ok
1/9=1present
3hours=xpresent
1/9 times x=3
multiplyboth sides by 9
x=27
answer is 27
another way is
1/9 hour=1 present
1hour=9present
3 hour=27 present
