Answer:

(x - 13) and (x + 3)

Step-by-step explanation:

Given

x² - 10x - 39

Consider the factors of the constant term (- 39) which sum to give the coefficient of the x- term (- 10)

The factors are - 13 and +3, since

- 13 × 3 = - 39 and - 13 + 3 = - 10, thus

x² - 10x - 39 = (x - 13)(x + 3) ← in factored form

PLEASE HELP ASAP! PLS
11Alexandr11 [23.1K]

Answer:

ok so it would take more effort to lift the 1 newton that is 4 m

Step-by-step explanation:

Work is done when a an object with a certain weight is moved at a given distance;

It is the product of force and distance and therefore varies directly to both distance and force.

Work = Force × distance;

For a 4 N box 0.5 m;

Work = 4 × 0.5

       = 2 Joules

For a 1 N box 4 m

Work = 1 × 4

       = 4 Joules

Therefore, Lifting a 1 N box for 4 m, will take more work

hope this helps

Leviafan [203]

Answer:

0.157 is the proportion of students who smoke.                                        

Step-by-step explanation:

We are given the following in the question:

Number of students who smoke = 58

Number of students who don't smoke = 311

Total number of students surveyed =

Number of students who smoke + Number of students who don't smoke

= 58 + 311\\=369

Proportion of students who smoke =

=\displaystyle\frac{\text{Number of students who smoke}}{\text{Total number of students}}\\\\= \frac{58}{369}\\\\= 0.157

Thus, 0.157 is the proportion of students who smoke.
