Solve the equation using the quadratic formula 3x^2 =2(2x+1)
2 answers:
3x² = 2(2x+1)
Expand the brackets
3x² = 4x + 2
Rearrange
3x² - 4x - 2 = 0
Quadratic formula is
(-b ± √(b² - 4ac)) / 2a
Where
a = 3
b = -4
c = -2
Therefore, putting these values in to the quadratic formula:
x = 15.487
or
x = -3.487
Round the answers how you will.
Step 1: Make equation equal to Zero
3x^2 = 4x + 2
3x^2 - 4x - 2
Step 2: use equation
a= 3 b = -4 c= -2
after plugging in answer should be
(2 + or - sqrt 10) / 3

I would either round it to the 10th or 100th place.
Answer:
Step-by-step explanation:
Formula = a^2 + b^2 = c^2
Putting values
= (31)^2 + (48)^2 = (51)^2
= 961 + 2304 = 2601
= 3265 = 2601
Both sides are not equal so it is not a right triangle
Answer:
A
Step-by-step explanation:
For both lines the slope is 5/2 or 2.5.
Since the y-intercept is zero for both, both the equations are:
y=2.5x
Or
y=5/2x
