Please help me Im confused on this problem

Answer:

b = 6 sqrt(2)

Step-by-step explanation:

Since this is right triangle, we can use the Pythagorean theorem

a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse

3^2 + b^2 = 9^2

9+b^2 = 81

b^2 = 81-9

b^2 = 72

Take the square root of each side

sqrt(b^2) = sqrt(72)

b = sqrt(36*2)

b = 6 sqrt(2)

What is the answer to x-1=-5-x

maria [59]

Answer:

$x=-2$

Step-by-step explanation:

We have the equation $x-1=-5-x$

In order to solve for x, we need to get all of the x's to one side and everything else to the opposite side

$x-1=-5-x$

First, we can add 1 to each side

$x=-4-x$

Now, we can add x to each side

$2x=-4$

Next, we can divide each side by 2

$x=-2$

And here is our answer.
