(6z 2 - 4z + 1)(8 - 3z).

1 answer:

7 0

Distributive property
a(b+c)+ab+ac
a(b-c)=ab-ac

(6z^2-4z+1)(8-3z)
move for nicety
(8-3z)(6z^2-4z+1)
distribute
8(6z^2-4z+1)-3z(6z^2-4z+1)=
48z^2-32z+8-18z^3+12z^2-3z=
-18z^3+48z^2+12z^2-32z-3z+8=
-18z^3+60z-35z+8

what is the length of a chord at a distance for 4 cm away from the centre of a circle of radius 5 cm

We must reject x = -3 because distance is positive.

The value of x is 3.

Chord = 2x

Chord = 2(3)

Chord = 6 cm
