What do you have to find?
do you just need to solve the problem with those numbers?
Answer:
-1.15
Step-by-step explanation:
Subtract 0.4 from −
0.75
.
From the recursive rule, you can tell the initial value is 3 and the common ratio is 12. The explicit rule is always
.. (n-th term) = (initial value)*(common ratio)^(n -1)
Subsituting the values you know, you have
.. an = 3*12^(n-1)
Answer:
x=9
Step-by-step explanation:
Multiply both sides by 2.
x+3= 12
Subtract both sides by 3.
x=12-3
x=9
The perimeter is the sum of all its sides.
That is for all triangles or polygons in general.
Good luck!
