Answer:
b
Step-by-step explanation:
Step-by-step explanation:
3/6=k/7
cross multiply then
6k=21
divide by the coefficient of k
k=3.5
Answer:
20s³ + 50s² + 32s + 6
Step-by-step explanation:
( 4s + 2 ) ( 5s² + 10s + 3)
use the distribution property:
20s³ + 40s² + 12s + 10s² + 20s + 6
combine like terms:
20s³ + 50s² + 32s + 6
therefore
the expand value = 20s³ + 50s² + 32s + 6
b – 2a – c
a = –7
b = 3
c = –7
3-2 (-7)-(-7)
3+14+7
17+7=24
