Answer:
x = 8 ± 2i√2
Step-by-step explanation:
√-1 is imaginary number i
Step 1: Write equation
(x - 8)² = -8
Step 2: Solve for <em>x</em>
- Square root both sides: x - 8 = √-8
- Factor out negative: x - 8 = √-1 · ±√8
- Simplify: x - 8 = ±i2√2
- Add 8 to both sides: x = 8 ± 2i√2
Answer:
60 in
Step-by-step explanation:
BD² = s² + s²
21.21² = 2s²
s² = 224.93205
s = 14.997734829
Perimeter = 4s
= 59.990939316
solution is (- 1, 1 )
given the 2 equations
2x - y = - 3 → (1)
x + y = 0 → (2)
add (1) and (2) term by term to eliminate the term in y
3x = - 3 ( divide both sides by 3 )
x = - 1
substitute x = - 1 in either of the 2 equations and solve for y
(2) : - 1 + y = 0 ( add 1 to both sides )
y = 1
solution is (- 1, 1 )

also Twenty One Pilots are awesome!
ok sorry i had to write something more for it to accept it lol
So you start in 0 and then cout back 3 times unyill you get to - 15 and that is how you use the number line for this problem
