4A = E , A=E/4-----(1)

B/4=E , B=4E-------(2)

C+4=E, C=E-4------(3)

D-4=E, D=E+4------(4)

Substitute all values in 5th equation,

A+B+C+D=100  =  E/4 + 4E + E-4+ E+4 =100

 E/4 + 6E = 100

25E = 400

E=16 ANS....

Construct a polynomial function with the stated properties.
11Alexandr11 [23.1K]

Step-by-step explanation:

f(x) = a [x - (-2)] [x - (-1)] (x - 3)

with a ≠ 0.

f(x) = a(x + 2)(x + 1)((x - 3)

Use f(4) = 10 to find a.

10 = a(4 + 2)(4 + 1)(4 - 3) = 30a

a = 1/3

f(x) = (1/3)(x + 2)(x + 1)(x - 3)
