Answer:
-0.25
Step-by-step explanation:
1-3= -2
9-2= 8
-2/8= -0.25
Answer: 4.5
<u>Step-by-step explanation:</u>
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
<em>the bottom of the integral is -2 </em>
=
=
= 
= 
= 
= 
= -3 + 1.5 + 6
= 4.5
2x2=4, 5x6=30
Not sure if they’re one expression, of so it’s (2x2)+(5x6)=34
Answer:
90 degrees since its vertical angle
