As already described above, the prime polynomial is that which can no longer be factored to yield a much simpler terms. From the given choices, that which cannot be factored is letter C.

Answer:

The correct option is c.

Step-by-step explanation:

Option a,

8x^2-10x-3

8x^2-12x+2x-3

4x(2x-3)+(2x-3)

(2x-3)(4x+1)

A prime polynomial cannot be written as a product of lower-degree polynomials. Therefore option a is not prime.

Similarly find the factors of other expressions.

8x^2+2x-3

8x^2-6x+4x-3

2x(4x-3)+(4x-3)

(2x+1)(4x-3)

Therefore option b is not prime.

8x^2-6x-3

This polynomial factored further and cannot be written as a product of lower-degree polynomials.  Therefore it is prime and option c is correct.

8x^2+23x-3

8x^2+24x-x-3

8x(x+3)-(x+3)

(8x-1)(x+3)

Therefore option d is not prime.

The area of square abcd is 7cm^2 <br><br>show that x^2+4x=3
AveGali [126]

Answer:

see explanation

Step-by-step explanation:

The area (A) of the square = s² ( s is the measure of the side )

Here s = x + 2 and A = 7 , thus

(x + 2)² = 7 ← expand left side using FOIL

x² + 4x + 4 = 7 ( subtract 4 from both sides )

x² + 4x = 3 ← as required

The length and width of a rectangle are in a 7:2 ratio. Find the width of the perimeter is 72.
scoray [572]
<span>length = 7x
</span><span>width = 2x

2(7x + 2x) = 72
7x + 2x = 72/2
9x = 36
x = 36/9
x = 4
</span>
width = 2x = 2 * 4 = 8 units<span>
