Answer:

Diameter = 9

Step-by-step explanation:

Let the diameter be represented as x.

Based on the secant-tangent theorem, the following equation representing the relationship between the segments would be:

(16 + x)(16) = 20²

256 + 16x = 400

Subtract 256 from each side

16x = 400 - 256

16x = 144

Divide both sides by 16

x = 144/16

x = 9

Diameter = 9

The Distributive Property allows you to say that 3(x − 1) = 3x −

Serga [27]

Answer:

$3x - 3$

Step-by-step explanation:

In the distributive property each value inside the parenthesis will be multiplied by the value outside the parenthesis.

In the expression 3(x - 1) it will look like:

$(3 . x) - (3 . 1)$

Then we multiply both value separately giving us:

$3x - 3$

So in conclusion it would be right to assume that.

$3(x - 1) = 3x - 3$

PLEASE HELP

7x²=9+x
so
for
0=ax²+bx+c

$x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}$
so

7x²=9+x
mins 9 from both sides and minus x
7x²-1x-9=0
a=7
b=-1
c=-9

$x=\frac{-(-1)+/-\sqrt{(-1)^2-4(7)(-9)}}{2(7)}$
$x=\frac{1+/-\sqrt{(-1)^2+4(7)(9)}}{2(7)}$
so the 4th one
