Step-by-step explanation:
41 because if you separate the parts the square and the triangle then you would have a square that is 16 sq in diameter and a triangle that is 25sq in diameter

if x increases by 51, f (x) increases by 9.
<u>Step-by-step explanation:</u>
Given function:

The above equation would have a constant slope as it seems to be a linear function. ‘x’, the coefficient of the variable x is the slope of the function. Here,

The rate of change of the function with respect to x referred as the slope of the function. Thus,


Given, x increases by 51. So, we have


Now solve for ΔF,

Thus, we have obtained that if x increases by 51, f (x) increases by 9.
