Answer:
x= 1/3 , -4/3
Step-by-step explanation:
9x^2 + 9x -4 =0
(3x-1) (3x+4) =0
x= 1/3 , -4/3
Answer:
(x + y)² =16
Step-by-step explanation:
hello :
(x + y)² = x²+y²+2xy and : x²+y² = 6 xy = 5
(x + y)² = 6+2(5)
(x + y)² =16
Answer:
- 25
Step-by-step explanation:
We rewrite the expression:
(2x + 7) / (3x-4) = (11/2)
We clear the value of x:
2 * (2x + 7) = (11) * (3x-4)
4x + 14 = 33x-44
4x + 14 = 33x-44
33x-4x = 14 + 44
29x = 58
x = 58/29
x = 2
Answer:
the value of x in the ratio StartFraction 2 x plus 7 over 3 x minus 4 EndFraction equals 11 over 2 is:
A. 2
