Find the area of a plane figure bounded by lines 1.y=x^2+2x+4, y=x+6 2.y=x^2+6x+5, y= - x^2-6x-11

4.5

Step-by-step explanation:

First, find the points of intersection by solving the system.

y = x² + 2x + 4

y = x + 6

Solve by substitution:

x² + 2x + 4 = x + 6   ⇒   x² + x - 2 = 0   ⇒   (x + 2)(x - 1) = 0   ⇒   x = -2, x = 1

Now, integrate from x = -2 to x = 1

   the bottom of the integral is -2

= -3 + 1.5 + 6

= 4.5

answer: c i think

step-by-step explanation:

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
