Viktor [21]

Answer:

$138

Step-by-step explanation:

We can first turn the words into a mathematical equation by substituting words with the information we have:

Total earning - ( Price of three books)

$180 - (Price of one book x 3)

$180 - ($14 x 3)

Finally, after we have created the mathematical equation, we solve it!

$180 - ($14 x 3)

$180 - $42

$138

If the solution of a polynomial fucntion is x=-5 then the linear factor is (x-5)
insens350 [35]

Answer:

No. It would be (x + 5)

Step-by-step explanation:

set each of the factors as equal to 0. So if you do x+5=0 then solve for x by subtracting 5 from both sides you get x = -5

The clue is to switch the sign from the factor to get the value of the variable and vice-versa.
