Answer:
see explanation
Step-by-step explanation:
These are the terms of a geometric sequence with n th term formula
= a 
where a is the first term and r the common ratio
r =
=
= - 
the first term a = 64, hence
= 64 
Not for sure but i think it is <span>-4 x^4 y^6 hope it helps</span>
The 2 angles given are vertical angles , which mean they equal the same.
Set the 2 equations to equal each other and solve for x:
7x-26 = 5x +10
Add 26 to each side:
7x = 5x + 36
Subtract 5x from each side:
2x = 36
Divide both sides by 2:
X = 36/2
X = 18
