Answer:

6

Step-by-step explanation:

The hypotenuse will always be equal to "c." You can put "a" or "b" as 8. This gives us a^2 + 8^2 = 10^2 which simplifies to a^2 + 64 = 100. From there, you simplify (subtract 64, giving you a^2 = 36, and then take the square root of a^2 & 36 to get a = 6 (because 6*6 = 36))

If x – 9 is a factor of x2 – 5x – 36, what is the other factor? x – 4 x 4 x – 6 x 6
Sergio [31]

Answer:

(x+4)

Step-by-step explanation:

Solve by factoring. Think about what numbers multiply to be -36 (the last term) BUT also subtract/add up to be -5, which is the middle term. The answer to this is 4 and -9. Therefore, the two factors are (x-9)(x+4)

Combine the like terms to create an equivalent expression<br> -k - ( - 8k)
Svetllana [295]

____________________________________________________

Answer:

7k

____________________________________________________

Step-by-step explanation:

We are trying to combine like terms with the expression: -k - ( - 8k)

We are pretty much solving it.

Solve:

-k - ( - 8k)

The "- ( -" turns into a plus sign.

So it would look like:

-k - -8k or -k + 8k

Now, you would finish solving

-k + 8k = 7k

C) Find the point of trisection of the line segment AB, where A<br> (-6, 11) and B (10, -3).
PtichkaEL [24]

Answer:

Step-by-step explanation:

Δx = 10-(-6) = 16

Δy = -3-11 = -14

(-6+16/3, 11-14/3) = (-⅔, 6⅓)

(10-16/3, -3+14/3) = (4⅔, 1⅔)
