Step-by-step explanation:

Since y varies directly with x,

y = kx, where k is a real constant.

When x = 4, y = 32.

=> (32) = (4)k, k = 8.

Therefore when x = -2,

y = kx = (8)(-2) = -16.

Given :-

x/2 = 3

To Find :-

The value of 2x + 2 .

Solution :-

The given equation to us is ,

$\longrightarrow$ x/2= 3

$\longrightarrow$ x = 3*2

$\longrightarrow$ x = 6

Now we need to find out ,

$\longrightarrow$ 2x + 2

$\longrightarrow$ 2(6) + 2

$\longrightarrow$ 12 + 2

$\longrightarrow$ 14

Hence the required answer is 14.

Which completely describes the polygon

deff fn [24]

Answer:

None of the above.

Step-by-step explanation:Yes, all of the sides match, which would make it an equilateral polygon. However, it is not an equiangular polygon because not all of the angels are the same. In this case, since the angles do not mach and only the sides do, this is not a regular polygon. This is what leads me to believe that is none of them. All of the sides must be congruent and all interior angles must also be congruent.

The Surface area of the cube will be 433.5 square feet. Then the correct option is C.

<h3>What is a surface area of a cube?</h3>

Suppose that: The side length of the considered cube is L units. Then, we get:

Surface area of that cube = 6L² square units.

Bella is wrapping a cube shape box that measures 8.5 inches along each side.

The edge length of the cube is 8.5 meters.

Then the Surface area of the cube will be

Surface area = 6 x 8.5²

Surface area = 6 x 72.25

Surface area = 433.5 square feet

The Surface area of the cube will be 433.5 square feet.

Then the correct option is C.

More about the surface area of the cube link is given below.
