okay so first let's identify all the like terms in this equation

- 8 & - 22

-5a^2, - 19a^2, 12a^2

-5a, -14a, -2a

we can combine each of these sets of like terms separately and then write them all out together

so combining - 8 and - 22 is - 30

- 5a^2 and -19a^2 is -24a^4, then combining it with positive 12a^2 leaves you with -12a^2

-5a, -14a, - 2a is - 21a

so we have - 30 - 21a - 12a^2 as a finished result

however if your teacher wants you to factor then you have:

3(-7a - 4a^2 - 10)

or

-3(7a + 4a^2 +10)

What is the length of the dotted line in the diagram below? Leave your answer in simplest radical form.
Pachacha [2.7K]

Answer:

\sqrt{93}

Step-by-step explanation:

8^2+5^2=c^2

64+25=c^2

89=c^2

c=\sqrt{89} <-- this is the length of the rectangle at the bottom

2^2+(\sqrt{89})^2=c^2

4+89=c^2

c=\sqrt{93}  <-- length of dotted line (diagonal)

(-1, 5) because if you plug in -1 to both equations, you should get 5 from both equations. They also cross at that point, making that the solution.
