A because if you use T3 it wouldn’t have make sense so only reasonable and solution that works is A
H²+10h+21 = 0
h²+3h+7h+21 = 0
h(h+3)+7(h+3) = 0
(h+3)(h+7) = 0
h+3=0
h = -3
h+7=0
h=-7
Answer:
4n+1
Step-by-step explanation:
Term 1: 4(1)+1 = 5
Term 2: 4(2)+1 = 9
Term 3: 4(3)+1 = 13
Term 4: 4(4)+1 = 17
As far as I know 0 IS a rational number. The only ones that are not rational are negative numbers. :) Though I could be wrong.....
A^2+2a=195
Quadratic Formula,
a=13,-15
