Answer:
The LCM is 168
Step-by-step explanation:
The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.
x³ + 8x² + 11x - 20 ← the first on list
given the roots of a polynomial, say x = a, x = b and x = c
then the factors are (x - a), (x - b) and (x - c)
the polynomial is the product of the factors
f(x) = (x - a)(x - b)(x - c)
here x = - 5, x = - 4 and x = 1, hence factors are
(x + 5), (x + 4) and (x - 1)
f(x) =(x + 5)(x + 4)(x - 1) ← expanding factors gives
f(x) = (x² + 9x + 20)(x - 1) = x³ + 8x² + 11x - 20

Answer:
x =1
y = 3
Step-by-step explanation:
8x - 3y = -1 ------ * 2 part (a)
-5x +2y =1 ------ * 3 part (b)
16x -6y = -2 part (c)
-15x +6y = 3
x = 1
8(1) - 3y = -1 part (d)
8-3y =-1
-3y = -9
y =3
