Answer:
1.) -4x+30y 2.) distributive property 3.) -4x+30y, (-0.4(3)+3(2)), 10(-1,2)+10(6), -12+60, =48
Step-by-step explanation:
10(-0.4x+3y)= 10(-0.4x)+10(3y)= -4x+30y
10(-0.4(3)+3(2))
10(-0.4(3))+10(3(2))
10(-1.2)+10(6)
-12+60
= 48

Answer:D
Step-by-step explanation:
(3x^3 - 5x^2 + 4x - 9)-(7x^3 - 8x^2 - 5x + 10)
open brackets
3x^3 - 5x^2 + 4x - 9 - 7x^3 + 8x^2 +5x - 10
Collect like terms
3x^3-7x^3-5x^2+8x^2+4x+5x-9-10
-4x^3+3x^2+9x-19
