The correct answer is the first option, which is:
(–7 + i) + 7i = –7 + (i + 7i)
The explanation is shown below:
1. By definition, in the associate property of addition you summ the number by grouping them with parenthesis, without matter where you use those parenthesis.
2. Therefore, as you can see, you can obtain the result of the addition by agruping the numbers <span>(–7 + i) + 7i or –7 + (i + 7i)</span> .
Answer:
Scale factor = 1/8
Step-by-step explanation:
The formula would be
Number of miles × scale factor = 5 inches
Number of miles = 40 miles
Hence,
40 miles × scale factor = 5 inches
Scale factor = 5/40
Scale factor = 1/8

Answer:
10 feet
Step-by-step explanation:
Given that the distance to be reached is 8 feet above ground and she she placed a ladder so that it reached the bottom of the window, the base of the ladder was 6 feet from the house, the length of the ladder considered with the other lengths forms a right angled triangle.
The length of the ladder represents the hypotenuse side hence using pythagoras theorem
F^2 = 8^2 + 6^2
where F is the length of the ladder in feet
F^2 = 64 + 36
= 100
find the root of both sides
F = 10 feet
The ladder is 10 feet long
