In the sequence 5,10,20,40,80.. I can see that it is doubled each time.
Doubling 5 is 10, doubling 10 is 20, doubling 20 is 40, and doubling 40 is 80.
Good luck! Stay safe!

Why because you multiply x which is 2
Answer:
Step-by-step explanation:
(x + 4)^2 - 2 = 7 simplifies to
(x + 4)^2 = 5
We must isolate x. To do this, take the square root of both sides, obtaining:
x + 4 = ±√5
There are two roots/solutions. They are:
x = -4 + √5 and x = -4 - √5
You must include the square root operator (√). Use " ^ " to denote exponentiation.
Answer:
<x = 53 degrees
Step-by-step explanation:
<Q = 62 degrees (alternate angle)
<PRQ = 180-115 (Angles on a straight line add up to 180 degrees)
<PRQ = 65 degrees
<u><em>Now, Finding <x</em></u>
To find <x, we'll simply subtract 180 from rest of the triangles interior angles because the interior angles of a triangle add up to 180 degrees
=> <x = 180-65-62
=> <x = 53 degrees
