For this case suppose that we have a quadratic equation of the form:
The solution to the quadratic recuacion is given by:
Where,
The discriminant is:
When the discriminant is greater than zero, then the root is positive, and therefore, we have two positive real solutions.
Answer:
B. it has two real solutions
Answer:
The answer is 1.
Step-by-step explanation:
Answer:
8.7
Step-by-step explanation:
formula
d = sqrt(s^2 + s^2 + s^2)
d = sqrt(3*5^2)
d = sqrt(75)
d = 8.7
Where did I get the formula? If the cube sits on one of its faces then the diagonal of that face is sqrt(s^2 + s^2) = sqrt(2s^2)
Now to get the third s^2, you have to realize the the diagonal you calculated in the previous remark is one of the legs for the cube's corner to corner diagonal. The other leg is the height squared which is also s^2.
Answer:
x=0
Step-by-step explanation:
(x + 2)(2x + 3) = 6
mulitiplay values we get
2x² +3x+4x+6 =6
2x²+7x+6=6
Subtract 6 from both side we get
2x²+7x+6-6=6-6
2x²+7x=0
Xtaking X common
x(2x+7)=0
divide with (2x+7) on both side we get
x=0

The graph crosses the x-axis at the point (6, 0).
Answer is The constant x-value is 7, so the equation is x = 7.
