What are the values of a and b?

Mathematics
1 answer:
aleksklad [387]2 years ago
6 0

Answer: A

Step-by-step explanation: While I'm sure there is an equation to solve this which I don't remember I used process of elimination to solve this, there are two right triangle and one of the triangles is sides a, 2, and b. Since B is across from the right angle, it is the hypotenuse, therefore b is greater than a, that means d and b cannot be correct, since a is the same in a and c, we can assume a=8, using Pythagorean Theorem. 8^2 + 2^2= b^2.

b^2 = 68

the square root of 68 can be simplified to 2 * square root of 17

Use the Distributive Property to write each expression as an equivalent algebraic expression.
Romashka [77]

Answer:

9x - 45

Step-by-step explanation:

To simplify this expression, we need to use Distributive Property to get rid of the parentheses. So, we multiply the -9 by everything inside the parentheses.

-9(-x + 5)

-9 · -x = 9x

-9 · 5 = -45

Now we add our products together.

9x + -45

Since there is a '+' sign and a '-' sign next to each other, we can simplify it to just a '-'.

9x - 45

Hope this helped! Let me know if you have any other questions! :)
