P(-5) = (-5)³ - 6(-5)² - 7(-5) + 60

p(-5) = -125 - 6(25) - (-35) + 60

p(-5) = -125 - 150 + 35 + 60

p(-5) = -275 + 95

p (-5) = -180

so is x + 5 a factor of polynomial ( NO) because when make a substitution by -5 the answer will not be 0

Peter is placing a rectangle in the coordinate plane. He knows that the shorter side of the rectangle is one-third the length of

katrin [286]

Answer:

$(0,a)$

Step-by-step explanation:

Let

x-------> the length side of the rectangle

y------> the width side of the rectangle

we know that

$y=\frac{1}{3}x$ ---> equation A

$x=3a$ ---> equation B (given problem)

substitute equation B in equation A

$y=\frac{1}{3}3a=a$

the coordinate of the top-left vertex of the rectangle is equal to

$(0,a)$
