Answer:
no
Step-by-step explanation:
perpendicular means that they intersect at a 90° angle
So, we know that a^2 + b^2 = c^2. Right? That is called the Pythagorean Theorem.
In this case. We can say that 39 is a, 40 is b, and x is c.
NOTE: It doesn't really matter whether 39 is a or b. a & b are just the two legs of the right triangle.
So, if we say that 39 is a, 40 is b, and x is c. We can plug it into the Pythagorean Theorem.
39^2 + 40^2 = x^2
I'll let you take it from there.
Answer:
The formula to find the nth term of the given sequence is 54 · 
Step-by-step explanation:
The formula for nth term of an geometric progression is :
In this example, we have 
= 36 (the first term in the sequence) and
r = 
(the rate in which the sequence is changing).
Knowing what the values for r and are, now we can solve.
= 
= 54 ·
Therefore, the formula to find the nth term of the given sequence is
54 ·
Perimeter = (x+2) + x + (x+2) + x
Perimeter = 4x + 4
Area = x(x+2)
Area = x^2 + 2x
