Answer:
Step-by-step explanation:
in complex number land there are two distict parts real.. the first number and imaginary.. the second number with the i
if your problem really only has a 7 and an i in it.. then it looks like below
7 * i = 7i
but..I suspect you just left out a bit of the problem.. repost .. i'll answer it again if the problem is different that what you posted already :)
Answer:
Part A
T-Shirt: $6.00
Pants: $13.33(repeating decimal)
Earrings: 7.50(terminating decimal)
Part B
add $6+ $13.33+ $10 = $29.33
Answer:
25ft
Step-by-step explanation:
12 inches = 1 ft. Hence,
120 inches = 10 ft.
Likewise,
1 yard = 3 ft
5 yards = 15 ft
Hence, the length of both cars together is,
10 ft + 15 ft = 25 ft
<span>Simplifying
X2 + -4 = 0
Reorder the terms:
-4 + X2 = 0
Solving
-4 + X2 = 0
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + X2 = 0 + 4
Combine like terms: -4 + 4 = 0
0 + X2 = 0 + 4
X2 = 0 + 4
Combine like terms: 0 + 4 = 4
X2 = 4
Simplifying
X2 = 4
Take the square root of each side:
X = {-2, 2}</span>
