Answer: x = (sqrt(7) + 2)/3 and
x = ( – sqrt(7) + 2)/3
Explanation:
3x^2 - 4x - 1 = 0
Divide both sides by 3:
3x^2/3 - 4/3x - 1/3 = 0/3
x^2 - 4/3x - 1/3 = 0
x^2 - 4/3x = 1/3
x^2 - 4/3x + (2/3)^2 = 1/3 + (2/3)^2
(x - 2/3)^2 = 1/3 + 4/9
(x - 2/3)^2 = 7/9
Sqrt both sides:
x - 2/3 = sqrt (7/9)
x - 2/3 = |sqrt(7)/3|
Set x -2/3 = sqrt(7)/3
=> x = (sqrt(7) + 2)/3
Set x - 2/3 = - sqrt(7)/3
=> x = ( - sqrt(7) + 2)/3
Answer:
3 + 9
Step-by-step explanation:
Distribute the 3 to both numbers, so 3 x 1 = 3, and 3 x 3 = 9.
Answer:
If your taking about a triangle, the answer = .
Step-by-step explanation:
*^2= squared*
1)The formula to calculate the missing leg of a triangle is a^2 + b^2 = c^2.
Subsituting in the formula, 8^2+17^2=c^2.
2) Simplify values, 64+289=c^2, 353=c^2
3) find the square root of the value that is left, (square root)353=18.8 (rounded to 10th place).
4) 18.8=c
Answer:
y=1/2x+5
Step-by-step explanation:
- standard form: y-0=1/2(x- -10) *(x- -10) = (x+10)
- y=1/2x+5 which is now in slope-intercept
