What are the roots of h(x)=(x+5)(x+4) ?

- 5 and - 4

Step-by-step explanation:

( x + 5 ) ( x + 4 ) = 0

x + 5 = 0

x = - 5

x + 4 = 0

x = - 4

The roots are - 5 and - 4.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

answer: both chords and diameters have two endpoints on a circle. diameters must intersect the center of a circle.
