Answer:

15x -45
3(5x -15)

Step-by-step explanation:

The expression can be fully factored as ...

3·5·(x-3)

Equivalent expressions can be formed by eliminating parentheses to give ...

15x -45

or by combining different pairs of factors:

3(5x -15)
5(3x -9)

Of course any of the terms can be broken apart and/or combined in different ways:

= 15(x -2) -15

= (7x -7) + 2(4x -19)

2 angles of a triangle are the same size. the 3rd is 3 times as large as the 1st

myrzilka [38]

Answer:

36°, 36° and 108°

Step-by-step explanation:

let the equal angles be x then the third angle = 3x

The sum of the 3 angles in a triangle = 180°, thus

x + x + 3x = 180, that is

5x = 180 ( divide both sides by 5 )

x = 36

and 3x = 3 × 36 = 108

The 3 angles are 36°, 36° and 108°

Answer:

<em>Worker B needs 9 days to finish the rest of the work</em>

Step-by-step explanation:

<u>Proportions</u>

Worker A finishes a project on his own in 12 days and worker B does the same in 16 days.

Worker A does 1/12 of the project in one day and worker B does 1/16 of the project in one day. When working together, they do

$\frac{1}{12}+\frac{1}{16}=\frac{7}{48}$

After 3 days they have completed:

$3*\frac{7}{48}=\frac{7}{16}$

parts of the project, this means it still remains:

$1-\frac{7}{16}=\frac{9}{16}$

parts of the project and it is done by B alone. Since B does $\frac{1}{16}$ per day, he now takes

$\displaystyle \frac{\frac{9}{16}}{\frac{1}{16}}=9$

days to complete the project.

Worker B needs 9 days to finish the rest of the work
