Tony believes that x = -9 is a root of the polynomial x2 + 13x + 36. erika, however, believes that x = 4 is a root of the same polynomial. who is correct?

Multiply 36 and x together in such a way that the multiples add up to 13.

36x

9 and 4 add to 13

Divide and 4 by x.

(x + 9) (x + 4)

Set to zero.

(x + 9) (x + 4) = 0

x = -9

x= -4

Based on above, it is determined that Tony is correct.

x = -9, Tony's assumption is correct.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
