Answer:
(cx)2-(dy) 2
Step-by-step explanation:
Formula a2-b2= (a+b) (a-b)
By given formula
(cx)2 - (dy) 2 = (cx+dy) (cx-dy)
-4 is less than -5 even though they are both on the same side of the number line. -4 is closer to zero.
Answer:
48
Step-by-step explanation:
Here, the sides are in proportion.
⇒ 
⇒ 
⇒ k = 24 × 2
⇒ k = 48
28.7251 =
28 degrees
then take the decimal and multiply by 60 to get the minutes
so 0.7251 *60 = 43.506, use the whole number (43)
so now you have 28 degrees, 43 minutes
now take the remaining decimal ( 0.506) and multiply by 60
0.506*60= 30.36
when you have a decimal left over for the seconds, keep that as is.
so you now have 28 degrees, 43 minutes and 30.36 seconds
use ' for minutes and " for seconds
28 degrees 43' 30.36"
