Answer:
x2-30x-21=0
Step-by-step explanation:
x =(30-√984)/2=15-√ 246 = -0.684
x =(30+√984)/2=15+√ 246 = 30.684
The value of x in the given expression is; x = wz/y
<h3>How to change subject of formula?</h3>
We are given the expression;
w/x = y/z
Now, we want to find the value of x which means we want to make x the subject of the formula. Thus;
Multiply both sides of the given expression by x to get;
(w/x)*x = (y/z)*x
⇒ w = xy/z
Now, multiply both sides by z/y to get;
w(z/y) = (xy/z) * (z/y)
wz/y = x
Thus, the value of x in the given expression is;
x = wz/y
The correct question is;
If w/x = y/z, then what is the value of x

Answer:
Each number is 2 to the power some integers.
Step-by-step explanation:
The pattern is 4,8,16,32,64,128.
It follows the exponent of 2.
4=2*2 =
8=2*2*2=
16= 
32 =
64=
128 =
so, it is 2 to the power integers.
