Some people call 'n' "zero" for the first term, others call 'n' "1".
-- If n=0 for the first term, then T(0) = 0² + 3 = 3 .
-- If n=1 for the first term, then T(1) = 1² + 3 = 4 .
Answer:
x = 124°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
x = 180° - (32 + 24)° = 180° - 56° = 124°
Answer:
t = 2n + 3
Step-by-step explanation:
Given
4n = 2(t - 3) ← divide both sides by 2
2n = t - 3 ( add 3 to both sides )
2n + 3 = t
12 x 2 is 24 because its 12 doubled.
