Answer:
equilateral
Step-by-step explanation:
In an equilateral triangle, all sides and angles are equal.
Sn = n/2 (a1+an)
= 8/2 (3-38)
= 4 (-35)
= -140
Answer:
The new equation is 
Step-by-step explanation:
Given : Function
were shifted 7 units to the right and 3 down.
To find : What would the new equation be?
Solution :
Shifting to the right with 'a' unit is
f(x)→f(x-a)
So, shifting g(x) 7 units to the right is

Shifting to the down with 'b' unit is
f(x)→f(x)-b
So, shifting g(x) 3 units down is


The new equation is 
2 because it's the highest exponent in the expression
