Answer:
-20d^3 + 55d + 35.
Step-by-step explanation:
-4d(5d^2 - 12) + 7(d + 5)
= -20d^3 + 48d + 7d + 35
= -20d^3 + 55d + 35.
Answer:
Arts=295, Commerce=177
Step-by-step explanation:
That the three subjects have a common ratio implies that there is some common factor between them that relates to the actual number of students in each area, so 5:4:3 means 5x:4x:3x for some value of x
We know that there are 236 science students, so 4x = 236 or x = 59
so the number of arts students is 5(59) and the number of commerce students is 3(59)
Arts = 5*59 = 295
Commerce = 3*59=177
