its wierd but 2.22
Answer:
yes
Step-by-step explanation:
Answer:
3n+4 or n3+4
Step-by-step explanation:
7,10,13,16
they all have a difference of 3
so that's 3n
start with the first one: 3(1)+?=7
7-3=4
3n+4
use this for the other ones to double check
3(2)+4
6+4=10
<em>when we solve the equation it will become
x</em>² + 9x<em>= 0
now here a = 1 , b = 9 and c = 0
by using quaderatic formula
x = -b +,-</em>√<em>b </em>²<em>- 4ac / 2a ( 2a is divided by all terms )
by putting values
x = - 9 +,</em><em>- </em>√<em>81 / 2(1) ( </em>√<em>81 = 9)</em><em>
x = -9 + 9 / 2 and x = -9 -9 /2
x = 0 and x = -18 /2 = -9
now there are two values for x one is- 9 and other is 0
so we put -9 as the value of x then answer will be zero..</em>
