What you want to do is get x alone. So, divide both sides by -1/2 so x is alone. -12 divided by -1/2 is 24. Since this is an inequality you have to flip over your inequality sign when multiplying or dividing by a negative so your answer is now x>24
Zero. That number cannot go into that one
Answer:
it must also have the root : - 6i
Step-by-step explanation:
If a polynomial is expressed with real coefficients (which must be the case if it is a function f(x) in the Real coordinate system), then if it has a complex root "a+bi", it must also have for root the conjugate of that complex root.
This is because in order to render a polynomial with Real coefficients, the binomial factor (x - (a+bi)) originated using the complex root would be able to eliminate the imaginary unit, only when multiplied by the binomial factor generated by its conjugate: (x - (a-bi)). This is shown below:
where the imaginary unit has disappeared, making the expression real.
So in our case, a+bi is -6i (real part a=0, and imaginary part b=-6)
Then, the conjugate of this root would be: +6i, giving us the other complex root that also may be present in the real polynomial we are dealing with.
Answer:
Pyramid
V= 240 m^3
Step-by-step explanation:
The volume of a pyramid is 1/3 the Base times the height.
1/3x(10x8)x9
Let x be the length and y be the width of a rectangle.
Area = xy
When x and y are doubled
Length = 2x and Width = 2y
Area = 2x x 2y
Area = 4xy
-------------------------------------------------------------------------------------------------
Answer: When the dimension is doubled, the area is 4 times the original.
