Answer:

130z-3

Step-by-step explanation:

Break down the equation:

(9z^{2}-4)=

9z * 9z= 81z

You can't subtract 4, so I left it at (81z- 4)

(7z^{2}+ 1)=

7z * 7z= 49z

You can't add 1, so I left it at (49z+ 1)

Then Solve:

You can add 81z and 49z.

81z+49z= 130z

-4+1= -3

Hope this helps!

What is the distance between the points (-5, -2) and (3, 13)? if necessary, round your answer to two decimal places?
VikaD [51]
<span>In order to find the </span>distance<span> between the two points we utilize the </span>Pythagorean Theorem<span>,: </span>
<span>Distance = Square Root ( (X difference)^2 + (Y difference)^2 )</span>
So we have
Square Root (-5 -3)^2 + (-2 -13)^2 =
Square Root -8^2 + -15^2 =
Square Root (64 + 225)
