Answer:
80
Step-by-step explanation:
The "difference" means the answer using subtraction. Subtract -60 from 20 to find the different between the two numbers.
20 - (-60) When you have two minus signs, it become a plus sign.
= 20 + 60 Add
= 80 Difference between the numbers
Could you do it backwards? Subtract 20 from -60? Yes, but since the difference between two numbers will always be a <u>positive number</u>, you need to use absolute value symbols.
| -60 - 20 | Do -60 -20 first
= | -80 | Apply the absolute value of -80 (make the number positive)
= 80 Difference between the numbers
You do not have to put absolute value if you do 20 - (-60), but you can. For -60 -20, you must use them.
Therefore, the difference between 20 and -60 is 80.

2.5
Step-by-step explanation:
Answer:
AE=22.4
Step-by-step explanation:
BE is 1/2 of BC
BC is 20 cm All sides of a square are equal
BE = 1/2 BC Property of a midpoint.
BE = 10
Now just use Pythagorus
AB^2 + BE^2 = AE^2
AE^2 = 20^2 + 10^2 Perform the sqrs
AE^2 = 400 + 100 Add the terms
AE^2 = 500 Take the square root of both sides
√AE^2 = √500
AE = 22.36
AE ≈ 22.4
