Factor completely x3 + 7x2 + 3x + 21.
(x − 7)(x2 − 3)
(x + 7)(x2 + 3)
(x − 7)(x2 + 3)
(x + 7)(x2 − 3)

  (x + 7)(x^2 + 3)

Step-by-step explanation:

The two constant terms in the binomials must have a positive product, so both will have the same sign. This eliminates the last two choices.

The coefficient of x^2 is +7, which eliminates the first choice.

The factorization is shown by the second choice:

  (x + 7)(x^2 + 3)

A caret (^) is used to signify an exponent.

1; 35 is the ratio

step-by-step explanation:

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
