value of x is: x= i and x= -i
Step-by-step explanation:
We need to find the value of x from 
using quadratic formula.
The term is: 
The quadratic formula is:
Where a = 1, b=0,c=1
Putting values:
So, value of x is: x= i and x= -i

I think it’s 12, if you take $360 and subtract the $120 deposit you get 240 and i divided that by 20 to get 12.
Answer:
It is a perfect square. Explanation below.
Explanation:
Perfect squares are of the form
(
a
+
b
)
2
=
a
2
+
2
a
b
+
b
2
. In polynomials of x, the a-term is always x.(
(
x
+
c
)
2
=
x
2
+
2
c
x
+
c

)
x

8
x
+
16
is the given trinomial. Notice that the first term and the constant are both perfect squares:
x
2
is the square of x and 16 is the square of 4.
So we find that the first and last terms correspond to our expansion. Now we must check if the middle term,
8
x
is of the form
2
c
x
.
The middle term is twice the constant times x, so it is
2
×
4
×
x
=
8
x
.
Okay, we found out that the trinomial is of the form
(
x
+
c
)
2
, where
x
=
x
and
c
=
4
.
Let us rewrite it as
x
2
+
8
x
+
16
=
(
x
+
4
)
2
. Now we can say it is a perfect square, as it is the square of
(
x
+
4
)
.
A=adult ticket s=student ticket
64a+132s=$1040
a=2s
128a+132s=$1040
260tickets=$1040
$1040/260=$4
s=$4 (1s=$4x1)
a=$8 (2s=$4x2)
132s=$528 (132x$4)
64a=$512 (64x$8)
TOTAL=$1040
Answer:
q = 2/3p - 3
Step by step:
2q+2p = 1+5q
2q - 5q = -2p + 1
-3q = -2p + 1
q = 2/3p - 3
