Answer: if you simplify this it becomes 30=28 but this is a false statement so you would say 30≠28
Step-by-step explanation:
≠ means not equal
Answer:
x = ±11i
Step-by-step explanation:
x^2 = -121
Take the square root of each side
sqrt(x^2) = sqrt(-121)
sqrt(x^2) = sqrt (-1) *sqrt(121)
We know that the sqrt(-1) is i
x = i ( ±11)
x = ±11i
Answer: 171 cm
Step-by-step explanation: im not sure if this is right but
9x12=108
9x7=63
108+63=171
Solve for <span>x </span>by simplifying both sides of the equation, then isolating the variable.<span>x=4</span>
