200-144=56
56/2=28
Neil is 28
Answer:
C) 20
Step-by-step explanation:
ab=15
5*3 = 15
which is a and which is b
a - b = +2
5 - 3 = + 2
------------------
a = 5 and
b = 3
------------------
a3-b3 = 53 - 33 = 20
According to what you are doing you can reverse the formula
Answer:
y = 3x + 1
Step-by-step explanation:
Consider the differences between consecutive terms of y
1 → 4 → + 3
4 → 7 → + 3
7 → 10 → + 3
10 → 13 → + 3
13 → 16 → + 3
The differences are constant, the constant is the multiplier, that is
y = 3x
Given the point (0, 1 ) , thus add 1 to the 3x term , hence
y = 3x + 1 ← equation relating x and y
The square root of 11025 is 105
