Since 3 divides 42, 3xy itself is the greatest common factor of 3xy and 42xy.
Answer: 3xy
The area of a square with sides of length s is
A=s^2, and we are told A=25 so
s^2=25
s=√25
s=5m
4 (e)
sin^8 x - cos^8 x
= (sin^4 x + cos^4 x)(sin^4 x - cos^4 x)
= (sin^4 x + cos^4 x)(sin^2 x - cos^2x)(sin^2 x +cos^2 x)
= (sin^4x + cos^4 x)( sin^2 x- cos^2 x)
Sorry I cant do 4 (d).
Answer:
Step-by-step explanation:
Given Equation :

Using distribute property:

Adding the like terms we get :


Transposing the variables on the right side and constant terms on the left side :


Dividing both sides by 5 :


Answer:
Hey there!
The perimeter of the triangle is the distance around it.
We can find the distance of two points using the distance formula, and add up all the distances to find the total distance.
-4, -6 to 3, 3 is 2
3, 3 to 7, 2 is 5
7, 2 to -4, -6 is about 5.4
2+5+5.39=12.4, which is closest to 12.36.
Let me know if this helps :)
