Answer:
Step-by-step explanation:
First of all, subtract 12 from both sides of the equation to put it into standard form:
3x² +8x -12 = 0
Then identify the a, b, c of this form:
ax² +bx +c = 0
You see that a=3, b=8, c=-12.
Now use those values in the quadratic formula for the solutions:
Answer:
one
Step-by-step explanation:
Zero has one square root which is 0.
Negative numbers don't have real square roots since a square is either positive or 0.
3 consecutive even integers : x, x + 2, x + 4
x + (x + 2) + (x + 4) = -84.....combine like terms
3x + 6 = - 84.......subtract 6 from each side
3x = -84 - 6
3x = - 90...divide both sides by 3
x = -90/3
x = -30
x + 2 = -30 + 2 = -28
x + 4 = -30 + 4 = -26
so ur 3 numbers are : -26, -28, -30
Answer:
x = 6
Step-by-step explanation:
- Subtract 8 from both sides of the equation
- Simplify
- Subtract the numbers
- Divide both sides of the equation by the same term
- Simplify
- Cancel terms that are in both the numerator and denominator
- Divide the numbers
the radius is 8.917197452 in
