Express as a trinomial.
(3x + 1)(x + 9)

the answer is d. (1.2, -4.7) on edgn

hope this !

a: 1/6, j: 1/4

step-by-step explanation: you are welcome

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
