It Depends On What You are Making for Example If You Want To Make A Cupcake You Going To Measure And See How Many Cups Of Water and All The Things They Need To Make The Cupcake You Probably Need 3 Cups. You Should Be More Specific With Your Question.
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: B. x = 6</h3>
==========================================================
Explanation:
Since the vertical lines are parallel, this means the alternate exterior angles shown are congruent.
Set them equal to each other and solve for x.
15(x+2) = 120
15x+30 = 120
15x = 120-30
15x = 90
x = 90/15
x = 6
Or we could have the steps like this
15(x+2) = 120
x+2 = 120/15
x+2 = 8
x = 8-2
x = 6
1) x= -7
2) x= -5
3) x=-22
4) x =8
Not sure about the last one tho
I tried to help :)
1/3(21 - 3a) = 6 - a
7 - a = 6 - a
7 = 6
Therefore, the equation has no solution.
