It is not true because if you add in 0 the equation would be 8-4(0)=4(0)
4x0 = 0
so it would be 8-0=0 which doesn't add up.
s + j = 2m
s = 54
m = 60
54 + j = 120
j = 120 - 54
j = 66
Answer:
-15a² -14a+16
Step-by-step explanation:
2×8=16
2×5a=10a
-3a×8=-24a
-3a×5a=-15a²
16+10a-24a-15a² = -15a² -14a+16
