Answer:
Positive 8
Step-by-step explanation:
The end value of -(-8) would be positive eight because when you multiply a negative by a negative, you get a positive value.

Answer: z = 
Step-by-step explanation:
To find <em>z</em>, you must set up a proportion to solve.
To find the altitude of a special right triangle, the formula is:

You can use <em>5</em> as <em>a</em> and <em>2</em> as <em>b</em> to complete the proportion:

Next, to solve:
<u>Step 1</u>: Cross-multiply.

(5)*(2) = z*z
10 = z²
<u>Step 2</u>: Take square root.
10 = z²
√10 = z

Hi there! The answer is 0 solutions.

First we need to work out the parenthesis (for instance possible by using rainbow technique).

Now subtract 12.

Now we can see that the right side of the equation is always 8 smaller than the left side of the equation. Because the right is always smaller, this equation cannot be solved. Therefore there are no solutions to this equation. The answer is 0 solutions.
Hope you could understand.
