Surface area of the pyramid= 4*(area of the triangle) + area of the square
Area of the triangle = (1/2)*base*height=(1/2)*5*5= 25/2 in²
Area of the square = 5*5 =25 in²
Surface area of the pyramid = 4*(25/2) + 25=2*25 + 25=75 in²
A
i need to put 20 characters in here so imma tell you, just use desmos.com. if you type in the equations, it’ll show you the graph
Answer:
(b) It is symmetrical about 
Step-by-step explanation:
Given

See attachment for options
Required
True statement about the graph
First, we check the line of symmetric

Expand

Open bracket


A quadratic equation
has the following line of symmetry

By comparison, the equation becomes:



Hence, the line of symmetry is at: 
(b) is true.
