Multiply (3x-1)(-x+4)

iogann1982 [59]

Answer:

$-3x^{2}+13x-4$

Step-by-step explanation:

You can use the foil technique (first outer inner last)

(3x - 1)(-x + 4) = (3x · (-x)) + (3x · 4) + ((-1) · (-x)) + ((-1) · 4)

= $-3x^{2}+12x+x-4$

= $-3x^{2}+13x-4$

Luci cuts a board that is 5/7 yard long into pieces that are 5/14 yard long. How many pieces does she cut?

zvonat [6]

Answer:

So total number of pieces will be 2

Step-by-step explanation:

We have given the total length of the board $=\frac{5}{7}yard$

It is given that Luci cuts the board into pieces of $=\frac{5}{14}yard$ long

We length of each piece = $=\frac{5}{14}yard$

We have to find the total number of pieces

For finding total number of pieces we have to divide the total length of board by length of each piece

So number of pieces $=\frac{\frac{5}{7}}{\frac{5}{14}}$ = 2

Solve each system. y=7-3x 3x+y=10

ad-work [718]

Answer: 0 = 3

Step-by-step explanation: If y = 7 - 3x, we can plug that in for y in the equation 3x + y = 10 by writing it as 3x + 7 - 3x = 10.

- 7 - 7

--------------------------

3x - 3x = 3

0 = 3
