M = 7x² +21
Step-by-step explanation:
Subtract the unwanted terms on the left from both sides.

Step-by-step explanation:
answer of 16 number
h2=p2+b2 ,therefore
h=100+80
h=180
answer of question 17
h2=p2+b2
576=p2+104
576-104=p2
472=p2
N = 3 ( the next number is 3 plus the previous number
sequence formula = an = 3(n-1) +2
so for term the term that =59
59 = 3(n-1) +2
distribute:
59 = 3n -3+2
59 = 3n -1
60 = 3n
n = 60/3
n = 20
59 is the 20th term
