Solution:</h3>
A line of symmetry is a figure that can be <u>divided</u> in 2 equal parts.
- The first figure has 1 line of symmetry since it can be <u>divided</u> into 2 equal parts horizontally. (According to image)
- The second figure has 1 line of symmetry since it can be <u>divided</u> into 2 equal parts. (According to image)
Answer:

Step-by-step explanation:
A function satisfying the equation
is said to be an even function. This denomination comes from the fact that the same relation is satisfied for functions of the form
with
even. Observe that if
is twice differentiable we can derivate using the chaing rule as follows:
implies 
Applying the chain rule again we have:
implies 
So we have that function
is also an even function.
Answer:
letters = 46536
Step-by-step explanation:
letters + packages = 50995
letters + 4459 = 50995
letters = 50995 - 4459
letters = 46536

Answer:
x = 12
Step-by-step explanation:
The segment from the vertex to the base is a perpendicular bisector.
Using Pythagoras' identity on the right triangle on the right.
(
x )² + 3² = (
)² , that is
x² + 9 = 45 ( subtract 9 from both sides )
x² = 36 ( multiply both sides by 4 )
x² = 144 ( take the square root of both sides )
x =
= 12
