Question

Find x. A) 4 B) 5 C) 6.7 D) 9

Answer 1

Answer:

x=9

Step-by-step explanation:

3(3+x) = 4(4+5) distribute

9+3x=16 +20 combine like terms

9+3x=36 subtract 9 from both sides

-9       -9

3x=27 divide by 3

/3    /3

leaves x = 9

Can i have brainiest.

Answer 2

Answer:

Option D is correct

value of x is, 9

Step-by-step explanation:

If two secant segments are drawn from a point outside a circle,

then the product is given by":

$(A+B) \cdot B = (C+D) \cdot D$

As per the statement:

Given the circle.

Let A= 5, B = 4, C = x and D = 3

We have to find the value of x.

Using the formula of length of two secants:

$(A+B) \cdot B = (C+D) \cdot D$

then;

$(4+5) \cdot 4 = (3+x) \cdot 3$

⇒$9 \cdot 4 = (3+x) \cdot 3$

Divide both sides by 3 we have;

$3 \cdot 4 = 3+x$

⇒$12 = 3+x$

Subtract 3 from both sides we have;

9 = x

or

x = 9

Therefore, the value of x is, 9
