it is false because a sphere is basically a three- dimensional circle. It is a polyhedron.
Answer:
x = 14
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Subtract 8x from both sides.
Step 3: Subtract 18 from both sides.
Step 4: Divide both sides by -2.
To solve this question, we use the factor theorem, and using it, the polynomial function is:

------------------------------
The factor theorem means that if k is a root of f(x), f(k) = 0.
Thus, applying the factor theorem for this question, we have to choose the function for which: 
------------------------------
Function 1:

Testing the values:



Thus, since all three conditions are satisfied,
is the polynomial function.

From the given equation
105% * 90 = 200% * x
105/100 * 90 = 200/100 * x
105*90 = 200*x
x = 105*90/200
X = 21*9/4
X = 189/4
x = 47.25
Value of x = 47.25 or 47 1/4
