Which inequality represents all values of X for which the product below is defined?
goblinko [34]

Answer:

x ≥6

Step-by-step explanation:

Given the product:

√(x-6)*√(x+3)

The function has to be defined if x ≥0

Hence;

√(x-6)*√(x+3)≥0

Find the product

√(x-6)(x+3)≥0

Square both sides

(x-6)(x+3)≥0

x-6≥0 and x+3≥0

x≥0+6 and x ≥0 - 3

x ≥6 and x ≥-3

Hence the required inequality is x ≥6

Inessa [10]

Answer: OPTION D

Step-by-step explanation:

The formula for calculate the surface area of a rectangular prism is:

SA_{rp}=2(wh+lw+lh)

Where w is the width, h is the height and l is the length.

You can see in the figure attached that:

l=3.4ft

w=3ft

h=4.1ft

Therefore, when you substitute these values into the formula you obtain that the surface area is:

SA_{rp}=2[(3ft*4.1ft)+(3.4ft*3ft)+(3.4ft*4.1ft)]=72.88ft^{2}
