Answer:
2√3
Step-by-step explanation:
root 27
= √27
= 3√3
12 upon root 3
= 12 / √3
= ( 12 / √3 ) x ( √3 / √3 )
= ( 12 x √3 ) / ( √3 x √3 )
= 12√3 / 3
= 4√3
6 upon √3
= 6 / √3
= ( 6 / √3 ) x ( √3 / √3 )
= ( 6 x √3 ) / ( √3 x √3 )
= 6√3 / 3
= 2√3
root 3 = √3
root 3 + root 27 - 12 upon root 3 + 6 upon root 3
= √3 + 3√3 - 4√3 + 2√3
= 4√3 - 4√3 + 2√3
= 2√3
sub x=1, a(1)^2 +b(1) + c=0,
a+b+c=0______eqn 1
sub x=-1, a(-1)^2+b(-1)+c=2
a-b+c=2_______eqn 2
sub x=2, a(2)^2+b(2)+c=8
4a+2b+c=8______eqn 3
from eqn 1
c=-a-b
eqn2
a-b-a-b=2
-2b=2
b=-1
eqn3
4a + 2b -a-b=8
3a+b=8
3a+(-1)=8
3a-1=8
3a=9
a=3
c=-a-b
c=-3--1
c=-2
Answer:240
I know this is annoying but, i took the question in Edgenuity
c = (x + 3)^2
Step-by-step explanation:
(6/2)^2 = (36/4)
= 9
=x^2 + 6x + 9
= (x + 3)(x + 3)
c = (x + 3)^2
