that's the "secant segments from external point"  theorem... and that's just an example... so... use that for those

now, for the other two, you'd want to post them separately, one at a time, easier to track and revise

State an equation you could use to find the value of x. Then find the value of x in simplest form.
Alex17521 [72]
You can use the Pythagorean Theorem:

a^2+b^2=c^2
x^2+x^2=(7√2)^2
2x^2=49*2 (combine like terms and square the 7√2)
x^2=49 (divide both sides by 2)
x=7 (square root both sides)

So the equation is 2x^2=98 (simplest form) and x=7

Hope this helps

What value of x makes the following equation true?<br> 15+3x=3(2−2x)
Alinara [238K]

Answer:

\boxed {x = -1}

Step-by-step explanation:

Solve for the value of x:

15 + 3x = 3(2 - 2x)

-Use <u>Distributive Property</u>:

15 + 3x = 3(2 - 2x)

15 + 3x = 6 - 6x

-Take 6x and add it to 3x:

15 + 3x + 6x = 6 + 6x - 6x

15 + 9x = 6

-Subtract both sides by 15:

15 - 15 + 9x = 6 - 15

9x = -9

-Divide both sides by 9:

\frac{9x}{9} = \frac{-9}{9}

\boxed {x = -1}

Therefore, the value of x is -1.
