A square piece of paper has an area of x2 square units. A rectangular strip with a width of 2 units and a length of x units is c

vlabodo [156]

Let

x--------> the length side of the original square paper

we know that

the area of the original square paper is equal to

$A1=x*x=x^{2} \ units^{2}$

the area of the remaining piece of paper is equal to

$A2=x^{2} -2x\\ A2=120\ units^{2} \\ so\\ x^{2} -2x=120\\ x^{2} -2x-120=0$

therefore

the answer is the option

x2 − 2x − 120 = 0

(picture) Factoring Polynomials: GCF PLEASEE HELP!!!!! a b c d

kramer

For this case we must find the greatest common factor of both expressions, the GFC will be the greatest number that is a factor of both numbers, that is:

The number 4 is the greatest number that divides 32 and 12 resulting in a whole number.

$\frac {32} {4} = 8\\\frac {12} {4} = 3$

In addition, both expressions have as a common factor, $a ^ 2$ :

$4a ^ 2 (8a + 3)$

Thus, $32a ^ 3 + 12a ^ 2 = 4a ^ 2 (8a + 3)$

Answer:

$4a ^ 2 (8a + 3)$

Option A

Round 25,386 to the nearest 1,000

Gekata [30.6K]

25,386 to the nearest 1000 is 25,000. This is because 386 is less than 500, and it’s only when a number is over or equal to 500 that you round up to the next thousand.
