Answer: The area of the notebook that the sticker covers is 128 cm^2
Step-by-step explanation:
The equation for the area of a rectangle should be:

-The height of the stickers measures 16 cm:

-So, if the base is half as long as the height, you divide it by 2:

-Then, you substitute it:
· 
-Result:

4.50+4.50=9.00=9
+
2.39+2.39=4.78
+
1.99
=
15.77
15.77-25=-9.23
Answer:
C
Step-by-step explanation:
note y = f(x) = 0
y = 0 is the x- axis
We are looking for values of x on the x- axis where the graph crosses/touches
This occurs at
x = - 2, x = 1, x = 3 → C
Tan theta =3
theta =tan invesre 3
arctan 3 = tan⁻¹ 3 = 71º 33' 54.184"
