-23 is a correct answer
Step-by-step explanation:
(7m+2)/3=-11
7m+2=-33
7m=-33-2
m=-35/7=-5
So, 2×(-5)^3+10×(-5)^2+4×(-5)-3
= -250+250-20-3
= -23

Answer:
2m³+10m²+4m-3= -23
Step-by-step explanation:
( 7m+2)/3=-11
( 7m+2)=-11*3
( 7m+2)=-33
7m=-33-2
7m= -35
m=-35/7
m= -5
= 2m³+10m²+4m-3
= 2 * (-5)³+10*(-5)²+4*(-5)-3
= 2*(-125)+10*25-20-3
= -250+250-23-3
= -23
2m³+10m²+4m-3= -23
