5. Subtract -5a from - 3a
6. Evaluate a-4b+2 if a = 2,b= 1
7.add x³+ 2y²- 3xy and 5x³-2y²- 2by
8. Write product form of ( 1/4a)³ and 1/4 a³. Are they same??​

Answer 1

Step-by-step explanation:

5x-6

3y+9

two times the sum of y and 6

three time the difference of 6 and the number b

3)

-4

-5a-3a= -8a

a-4b+2=2-(4×1)+2=2-4+2= -2+2=0

6x^3-3xy-2by
