Which of the following is a factor of x3 + 343?
a: x − 7
b: x2 − 14x + 49
c: x2 + 7x + 49
d: x + 7

The factor of x³ + 343 is (x + 7). Option D is correct.

A factor of an expression is usually referred to as a number or an algebraic expression that divides the known expression.

The above algebraic expression needs to be expanded to determine its factor;

Mathematically;

Therefore, we can conclude that the factors are (x + 7) (x² - 7x + 49)

x + 7

Step-by-step explanation:

Since both terms are perfect cubes, factor using the sum of cubes formula, where a = x and b = 7

(x + 7) (x - 7x + 49)

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:

no oblique asymptote

step-by-step explanation:

to find the oblique asymptote of f(x)

here numerator has degree 1 and denomintor degree 2

degree of numerator < degree of denominator

hence there is no oblique asymptote

when the degree of the denominator > that of the numerator, we saw that the value in the denominator got so much bigger, so quickly,   giving us a horizontal asymptote of the x-axis. or we can write

f(x) = a polynomial of x + a proper fraction.

in this case only we have oblique asymptotes but not when numerator has less degree.
