Answer:she is correct less than 90 degrees
Step-by-step explanation:
N is the term that you are looking for. it asked for the 3rd term so you replace n with 3. now its : 3 x 3^2 + 4 . you use the order of PEMDAS:
P arenthesis
E xponents
M ultipication
D ivision
A ddition
S ubtraction
you start with parenthesis but there are none so now exponents. 3^2 is 3 x 3. that would be: 3 x 3 = 9.
now multiplication. 3 x 9 + 4. 3 x 9 = 27
now division. there is none. so now addition and there is. 27 + 4 = 31.
then subtraction but there is none. so now you are done.
the 3rd term is therefore 31.
i hope that i helped.
Let x = 1st positive integer
Let x + 1 = 2nd positive integer
As give, their sum of squares is 841
factor 2 out,
(x+21)(x-20)
This gives, x=20 and =-21 (neglect the negative value)
So, x = 20
x+1 = 21
So, the two numbers are : 20 and 21
