Answer:
Step-by-step explanation:
3b⁵ + 15b⁴ - 18b⁷ = 3b⁵ + [3*5*b⁴] - [6*3*b⁷]
=3b⁴*( b + 5 - 6b³)
4=$17.60
1=$17.60/4
1=$4.40
Hole this helps :)

Order of Operations is what you have to use
2(x+4) = 12
or, 2x + 8 = 12
or, 2x = 12-8
or, 2x = 4
or, x = 4÷2
hence, x = 2
10(-2*-2*-2)(-3*-3)
=10(-8)(9)
=-720
