Yep his right and it is shown to me good
5th term / 2nd term = r^4 / r = r^3
r^3 = 162/-6 = -27
so r = -3
a1 * r-3 = -6 so first term = 2
an = 2. (-3)^(n-1) Answer
Its B
<u>In a parallelogram,</u>
⇒the angles adjacent to each other
⇒ are of the same measure
⇒so
∠A = ∠C
∠B = ∠D
<u>Let's solve</u>:


<u>Let's check</u>:
⇒ for all quadrilaterals like a parallelogram
⇒all the angle measures added up to 360, so:

<u>Thus</u>:
<u>Answer: w = 20 and z = 15</u>
Hope that helps!
Answer: C
Step-by-step explanation: The opposite of a positive integer (18) is -18
