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

A machine paints 34o toy boats im 3/4 of an hour how many boats can he make per hour
leonid [27]
Here, we can set up a proportion:

34 ÷ 3/4 = ? ÷ 1
34*1 = 34
34÷3/4 = the time needed to build one toyboat

34/3/4 = 45.3333333333

45.3 repeating is not a whole number, so we need to approximate. 

45 is the closest whole number, 

So.. a machine can paint 45 toy boats per hour. 

I really hope that helped! :)

Can someone help with this I didn’t pay attention in math and I have homework ‍♀️
Lady bird [3.3K]

Answer:

C.

Step-by-step explanation:

Even though it is absolute value, 17 is still the greatest answer. If a number is in absolute value it will never be negative, only positive values can come out of an absolute value.

An example for absolute value would be if you had to measure the amount of distance away from something, even if its behind you, it would still be a positive number of length away from you.

If you had the absolute value of -25, it would automatically be equal to 25.

So circling back to the original problem, the absolute value of 17 would be greater than 3, -4 and -8. If (hypothetically) it was the absolute value of -17 it would still be greater because it would equal 17.

I hope that made sense, im sorry that it's a bit lengthy. Have a good day :)

Pls Help! Very Easy! 10 points! Brainliest if you are correct!
SSSSS [86.1K]
We can see that the 33 degrees corresponds to angle A (parallel lines) meaning they’re equal.
This means that 33 + 2x = 5x (5x is the exterior angle, so the other two interior angles’ sum must equal to it)
3x = 33
x = 11

Answer:

answer and explanation below

Step-by-step explanation:

2.m<x=75(angle on the same line so 180-105)

  m<y=105 (vertical angles of the parallelogram are equal)

 m<z=75 ( vertical angle of m<x)

3.M<y = 25 ( vertical angle property)

m<z=155( on the same line)

m<z and M,x =155( vertical angles )
