5x2y-5x2+3yx2-3y2+x2-y2+8xy2-3y2
First Collect like terms:
5x x 2y, +3x x 2,and +8xy x 2
16x x 2y -4x x 2 - 4y x 2—> Multiply the numbers:
Multiply the numbers 16 x 2
16 x 2 = 32
Now multiply the numbers 4 x 2
4 x 2 = 8
Now Multiply the numbers 4 x 2 again
4 x 2 = 8
= 32xy - 8x- 8y
Factor 8 from the expression
Final Answer:
8(4xy-x-y)
I’m not really sure about my answer but i hope it helps!
Sorry if its wrong..
Stay Safe guys!
Answer:
125%
Step-by-step explanation:
lets just say the book is $100. 20% less would be $80
now to go back to $100, we need to add $20 to $80
20 is 25% of 80, so add the extra 25% to 100% of 80
Answer:-6h+15s
Step-by-step explanation:
7s+8s−6h
=7s+8s+−6h
Combine Like Terms:
=7s+8s+−6h
=(−6h)+(7s+8s)
=−6h+15s
Answer:
=−6h+15s
There are 2 formula to find the circumference of a circle.



is approximately 3.14
r is radius
D is diameter
and just a side note,

Hope that formula helps you :)
A) The car is moving 75 degrees to northeast because if the car Is going east and now going northeast. Clearly it's 75 degrees.
B) the angle would be 75 degrees because the angle because of the vertical angle ( vertical looks like a bow tie and the picture) and vertical angles are always the same.
C) The angle created by the turning is 105 degrees, remember the horizontal lines are 180 degrees and the other side if 3rd street would be 75 degrees, but subtract 75 from 180 you would get 105 degrees.
