--Multiplying Polynomials--Use the given formulas to express the volume of each object as a polynomial.

sasho [114]

32.

V = L*w*h

Where:

V= Volume

L= Length = x+5

w= width = x-2

h= height = 6

Replacing with the values given:

V= (x+5) * (x-2) * 6

V =[ (x*x) + (x*-2) + (5*X) +5*-2) ] * 6

V= [ x^2 - 2x + 5x - 10 ] * 6

V= [ x^2 + 3x - 10] *6

V= (x^2*6) + (3x*6)+ ( - 10 * 6)

V= 6x^2 + 18x - 60

The variable z is directly proportional to x, and inversely proportional to y. When x is 11 and y is 14, z has the value 7.85714

marta [7]

Z=kx/y

7.9=k11/14

Cross multiply

K11=7.9x14

K =7.9x14/11

K=10.1

........

Z= kx15/22

Z=10.1x15/12

Z=12.625
