Answer:
-15
Step-by-step explanation:
Given is a polynomial in x
We have to find the remainder when the above polynomial is divided by x+5
Remainder theorem says that f(x) gives remainder R when divided by polynomial x-a means f(a) = R
Applying the above theorem we can say that value of the function when x =-5
= Remainder when f is divided by x+5
= F(-5)
Substitute the value of -5 in place of x
= (-5)^4 + 12(-5)^3 + 30(-5)^2 - 12(-5) + 70
= 625-1500+750+60+70
= 5
Hence answer is 5
Total of 221 students
5 students in a van
6 buses fill with 216 students total
6x + 5 = 221
Consider this option:
way_1:
to substitute the given coordinates of A(5;6) and B(4;8) in every equation. Only 2x+y=16 belongs to the given points.
way_2:
to make up the equation of the line using coordinates of points A and B:
rule:
