Answer:
p = -8
Step-by-step explanation:
The equation is incorrect, is that what you wanted to find out?
Answer:
D
Step-by-step explanation:
Should work i got and 80 on that one
I would say A because every other question it shows the exact amount but since it says 20-29 you can’t really say the answer by looking at the graph unless you guess but that’s not what the question is saying it’s saying which question cannot be answered by looking at the graph and I would Say You cannot answer A by looking at the graph.
Sorry if I am wrong
Answer:

Step-by-step explanation:
to find the surface area we need to find the followng areas:
- area of a triangle and multiply it by 4 (because there are 4 triangles)
And once we have those areas, we add them to find the surface area.
Area of the square:
the formula to find the area of a square is:

where
is the length of the side: 
thus the area of the square is:


Area of the triangles:
the are of 1 triangle is given by

where
is the base of the triangle:
(the base of the triangle is the side of the square)
and
is the height of the triangle: 
thus, the area of 1 triangle is:



the area of the 4 triangles is (we multiply by 4):


finally we add the area of the square and the area of the 4 triangles to find the total surface area:
