Answer:
Step-by-step explanation:
4 6 10 18 34 66 130 n^2+2
1 4 9 16 25 36 49 n^2
2 4 8 16 32 64 128 2^n
2 6 12 20 30 42 56 n^2+n
this is Fibonacci, 1 1 2 3 5 8 13 21, and its hard to come up with a rule because you need to know the number one before and two before and add them together.
Answer:
yes :
use the following formula :
a^2 +b^2 = c^2
now apply it to the problem :
5^2+12^2=13^2
do the exponent :
25 + 144 =169
now add
169 =169
if they are equal , then it is a right triangle .
Answer:
x = -0.4
Step-by-step explanation:
Given:
-9x + 0.4 = 4
To move all constant to the right side of the equation, perform subtraction operation
That is, subtract 0.4 from both sides of the equation
-9x + 0.4 - 0.4 = 4 - 0.4
-9x = 4 - 0.4
-9x = 3.6
Perform division operation to isolate the variable
That is, divide both sides by -9
-9x / -9 = 3.6 / -9
x = -0.4
to be honest I agree that would be 6s
