Answer:
-15 then -10 = -25 we can only take one sign that accompanies the -10 and put in front of the brackets.
Step-by-step explanation:
-10 + (-15) = -25
just like (-15) -10 = 25
This is because ( ) is order of parenthesis Brackets first.
Answer:
length 28, width 22
Step-by-step explanation:
28 - 22 = 6, 28 x 22 = 616

Answer: 36.4 units (choice A)</h3>
===========================================================
Explanation:
Let's use the distance formula to find the distance from D to E
Note: uppercase D refers to the point, while lowercase d is the distance from D to E.
The length of segment DE is roughly 10.198 units long.
----------------
Repeat for the distance from E to F.
Segment EF is roughly 11.1803 units long.
----------------
Repeat for the distance from F to D.
Unlike the others, this result is exact.
----------------
Add up the three segment lengths to get the perimeter
DE + EF + FD
10.198 + 11.1803 + 15
36.3783
The perimeter is approximately 36.3783 units which rounds to <u>36.4</u>
The answer has been confirmed with GeoGebra.
Answer:
Option (4)
Step-by-step explanation:
Definition of a ray states that a segments which connects two points but extending only in one direction infinitely is called as Ray.
Opposite rays will have a common end but the direction of the arrows will be different.
Therefore, from the picture attached,
Opposite rays will be PA and PB.
Option (4) will be the correct option.
We are given this explicit formula :
In order to find eighth term let us plug n as 8 in this formula:
subtracting 8-1 first using pemdas rule
multiplying 5 and 7
subtracting 35-6
c(8) = 29
So eighth term is 29.
