Answer:
X1=-4+4i
X2=-4-4i
Step-by-step explanation:
X^2+8x+32=0
Δ=b^2-4ac=8^2-4(32)=-64<0
X1=(-b-i√Δ) /2a=(-8-8i)/2=-4-4i
X2=(-b+i√Δ) /2a=(-8+8i)/2=-4+4i
Answer: 3
Step-by-step explanation:
Distribute the 5: 15x-5=40
Add 5 from both sides: 15x=45
Divide 15 by both sides: 3
Answer: x/y that is distance/ speed which is the formula for time
Step-by-step explanation:
-2. All you’re doing is going from the number you start with and performing the opperations in the order they appear (-4+3-2+6-5=-2)
Answer:
22
Step-by-step explanation:
Put all the other numbers at the right side of the equation.
-3x + 25 + x + 21 = 2 is the same as -3x + x = -44
-2x = -44
-x = -22
x = 22
