Answer:

10)

a) y = 50+30x

b) y=50+30(2.5)

50+75 = 125

c) y = 2(50+30x)

d) y=2(50+30(2.5))

2(50+75)

2(125) = 250

13)

a) P = 2 ( L + W )

10x+2

b) A = W L

5x+1

c) for A its 15x+3 and for B its 54 x 2 + 18 x

Help please!!! Find the area of the shaded region. All angles are right angles

kompoz [17]

Answer:

Area = $147 m^{2}$

Step-by-step explanation:

The area of the shaded region is equal to the total area of the full square minus the area of the non shaded region.

The area of a rectangle is its base times its high

So A=b*a.

For the full square, A1= $9m*23m=207m^{2}$

For the non shaded square, A2 = $15m * 4m = 60m^{2}$

So the shaded area is A1-A2 = $207 m^{2} -60 m^{2} = 147 m^{2}$

Express the volume of the box as a polynomial in the variable x

Whitepunk [10]

The volume of the box as a polynomial in the variable x is x(12 - 2x)(7 - 2x)

<h3>How to determine the volume?</h3>

The complete question is added as an attachment

From the attached image, we have:

Length = 12 - 2x

Width = 7 - 2x

Height = x

The volume is calculated as:

Volume = Length * Width * Height

Substitute the known values in the above equation

Volume = (12 - 2x) * (7 - 2x) * x

This gives

Volume = x(12 - 2x)(7 - 2x)

Hence, the volume of the box as a polynomial in the variable x is x(12 - 2x)(7 - 2x)
