Then becomes
Answer:
12 in.
Step-by-step explanation:
You have to use the Pythagorean theorem for this problem. Since we are solving for DE, we do:
5 squared + b squared = 13 squared
25 + b squared = 169
Isolate the b:
25 - 25 + b squared = 169 - 25
b squared = 144
Find the square root of 144 = <u>12</u>
<u>(The formula for the Pyathagorean theorem is a squared + b squared = c squared) </u>
Answer: 4/15
Step-by-step explanation:
-1/3 - -3/5
Two negative signs become positive so it's
-1/3+3/5
Taking the LCM as 15,
-1/3= -5/15
3/5= 9/15
-5/15 + 9/15
= (-5+9)/15
= (9-5)/15 ( just changing the order without changing the sign)
= 4/15
This is the simplest form
(If you need it in decimal form is 0.26666... or 0.267)
