Answer:
We have the equation
we leave the terms with x on the left side of the equation and the independent terms on the right side.
resolving for x we have that
Since we need that the equation doesn't have solution, then it is necessary that the denominator of x be 0 and this occur when 
Then, for 
the equation hasn't solution
Answer:
729
Step-by-step explanation:
Each side of the cube measures 9cm
The volume of a cube is V^3
Therefore the volume can be calculated as follows
= 9^3
= 729

Answer:
X=18
Step-by-step explanation:
Isosceles means two sides are equal. In this case AC and BD are the same. So put both equations equal to each other and solve
Answer:
70
Step-by-step explanation:
So I assumed that the x was multiplication...so...15x3=45 and 33x5=165...so the perimeter is 210, so you divide that by 3 and the answer is 70!
