Answer: 4
The same since its in the center
20/360=X/72
Step-by-step explanation:
The discriminant of a quadratic is given as
, so we know that
When using the quadratic formula to calculate values for
, we have to take the root of the discriminant. There is no real answer to the root of a negative number and so the equation has no real roots.
There are two ways to find or determine for the value of
c. In the first method, we can use addition and subtraction to isolate the
variable c from the other variables. In the second method, we can use the
transposition of variables to isolate the variable c from the other variables.
So solving for the value of c:
<span>Using 1st method: Addition and Subtraction</span>
We are given:
240 = 6 z + c
Simply subtract 6 z on both sides:
240 – 6 z = 6 z + c – 6 z
Cancelling 6 z – 6 z on the right side:
240 – 6 z = c
or
c = 240 – 6 z
<span>Using the 2nd method: Transposition</span>
240 = 6 z + c
What we are going to do here is to simply transpose the
variable 6 z from the right side to the left side of the equation so that we
are left with c alone on the right side. Always remember that when we
transpose, the symbol becomes opposite. That is:
240 + (- 6 z) = c
240 – 6 z = c
or
<span>c = 240 – 6 z</span>
Each term is increasing by *3
Next three terms:
6, 18, 54
An impossible event is one that has no chance of happenening so x = 0 in this case or B
