Answer:
P(x) = x² - 15x + 50
Step-by-step explanation:
We write the polynomial function P(x), given that P(x) = 0 has the given roots, x = 5 and x = 10.
Since x = 5 and x = 10 are the roots of P(x) = 0, it follows that (x - 5) and (x - 10) are factors of P(x) = 0. So, P(x) = (x -5)(x - 10) = 0
Expanding the brackets, we have
x² - 10x - 5x + 50 = 0
Simplifying, we have
x² - 15x + 50 = 0 = P(x)
Thus,
P(x) = x² - 15x + 50
Answer:
i think its C. because its a negative number and you need to go a 4th of a 3rd of the way
Step-by-step explanation:
They have to be at least 40 abut less than 70, so 40 < (underlined) x < 70.
<span>They have to be at least 60 inches but less than 75 inches tall, so 60 < (underlined) y < 75. </span>
<span>Graph the following lines: </span>
<span>x = 40 </span>
<span>x = 70 (dotted) </span>
<span>y =60 </span>
<span>y= 75 (dotted) </span>
<span>The square the four lines make is the answer. I hoped that help!</span>
