(x+9)(x+2)=4(x+9) what is the value ofx

x = - 9, x = 2

Step-by-step explanation:

Given

(x + 9)(x + 2) = 4(x + 9) ← expand factors on left using FOIL

x² + 11x + 18 = 4x + 36 ( subtract 4x + 36 from both sides )

x² + 7x - 18 = 0 ← in standard form

(x + 9)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 9 = 0 ⇒ x = - 9

x - 2 = 0 ⇒ x = 2

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
