Answer: -64z
Step-by-step explanation: I assume you mean the 2 is an exponent, so -8z x -8z = -64z.

To determine whether a cause-effect relationship exists between two variables, a researcher must use an experimental approach.
<h3>What is
cause-effect relationship?</h3>
A cause-and-effect relationship is one which satisfies some conditions like:
- two events occur at the same time and in the same place
- one event immediately precedes the other
Therefore, To determine whether a cause-effect relationship exists between two variables, a researcher must use an experimental approach.

Answer:
15 units
Step-by-step explanation:
ΔABC is right with ∠C = 90° and AB the hypotenuse
using Pythagoras' identity on the triangle
AB² = AC² + BC² , hence
BC² = AB² - AC² = 17² - 8² = 289 - 64 = 225
⇒BC = 
= 15 units
Answer:
Step-by-step explanation:
Given
on solving this mixed fraction we get;
Now adding these fractions by same denominator method.
![-\frac{29\times3}{10\times3} +[-\frac{64\times2}{15\times2} ]\-\frac{87}{30} +[-\frac{128}{30}]\ = -\frac{215}{30}](https://tex.z-dn.net/?f=-%5Cfrac%7B29%5Ctimes3%7D%7B10%5Ctimes3%7D%20%2B%5B-%5Cfrac%7B64%5Ctimes2%7D%7B15%5Ctimes2%7D%20%5D%5C-%5Cfrac%7B87%7D%7B30%7D%20%2B%5B-%5Cfrac%7B128%7D%7B30%7D%5D%5C%20%3D%20-%5Cfrac%7B215%7D%7B30%7D)
X = 38
2x is equal to the angle next to the x + 66 angle because ℓ1 ∥ ℓ2 is parallel so:
2x + x + 66 = 180 -- combine like terms
3x + 66 = 180 -- subtract 66 from both sides
3x = 114 -- divide by 3 on both side
x = 38
