write an expression that describes the length of a rectangle given that the width is 2z and the area is 16z^3-10z^2+2z

3z + 1

Step-by-step explanation:

Area = 16z^2 - 10z^2 + 2z = 6z^2 + 2z = 2z(3z + 1)

Width = 2z

Area of a rectangle is given as:

Area = length × width

hence length = Area/Width

= 2z(3z + 1)/2z

= 3z + 1

3z + 1

Step-by-step explanation:

Area = 16z^2 - 10z^2 + 2z = 6z^2 + 2z = 2z(3z + 1)

Width = 2z

Area of a rectangle is given as:

Area = length × width

hence length = Area/Width

= 2z(3z + 1)/2z

= 3z + 1

The total nom of  code that can be used is equal to 5+3 = 8

The answer is in the image 

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53
