This is actually pretty easy.
<span>Simplifying 4n + -9 = -9 Reorder the terms: -9 + 4n = -9 Add '9' to each side of the equation. -9 + 9 + 4n = -9 + 9 Combine like terms: -9 + 9 = 0 0 + 4n = -9 + 9 4n = -9 + 9 Combine like terms: -9 + 9 = 0 4n = 0 Solving 4n = 0 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Divide each side by '4'. n = 0 Simplifying n = 0

****hope this helps!!!! please put as brainliest if possible!!!! really appreciated!!

Hello please help me with this I need an answer immediately thank you so much see image

For this case, we know that:

PA = PB

Then, by Pythagorean theorem (right triangle on the right) we have:

CP ^ 2 = CB ^ 2-PB ^ 2

So, again using the Pythagorean theorem (right triangle on the left) we have:

CA ^ 2 = CP ^ 2 + PB ^ 2

Substituting values:

CA ^ 2 = (CB ^ 2-PB ^ 2) + PB ^ 2

Rewriting:

CA ^ 2 = CB ^ 2

CA = CB

CA = 15

Answer:

The value of CA is given by:

CA = 15
