Answer:

None of the option

Step-by-step explanation:

Given :

(7-3i)+(x-2i)^{2} -(4i^{2} +x^{2} )

(7-3i)+(x^{2}+4i^{2}-4xi)-(-4+x^{2})      Since, i^{2} =-1

(7-3i)+x^{2}-4-4xi +4-x^{2}

7-3i-4xi

7-i(3+4x)

Therefore, None of the option is correct.

Answer:

The answer to your question is: letter A

Step-by-step explanation:

See the picture below

When we divide the polynomial by the factor the result is zero, that's why letter A is the factor.

When we divide the polynomial by B, C or D the residue is not zero, then they are not factors.

What is the volume of the right rectangular prism?
Ivahew [28]
I saw the image that should have been included in this problem.

It was a rectangular prism. It can also be identified as a right prism because its bases are aligned one directly above the other and its lateral faces are rectangular.

The image has the following measurements:
length = 7 inches
width = 5 inches
height = 4 inches

volume = length * width * height
v = 7 in * 5 in * 4 in
v = 140 in³  Choice B i believe.

Answer:

Commutative property of multiplication

Step-by-step explanation:

Commutative property of multiplication basically means that the order in which you multiply numbers does not matter.

For exampe:

3 x 4 = 4 x 3

    12 = 12

In your case:

5 x 7 x 4 = 5 x 4 x 7

        140 = 140

If we break that down:

5 x 7 x 4 = 5 x 4 x 7

   35 x 4 = 20 x 7

        140 = 140
