Answer:
the answer is a because ots increased by 8 inches
The sum of a number and three is (n+3)
The difference of 8 and the number is (8-n)
And if we multiply them we get:
(n+3)(8-n) if you wanted it expanded...
8n-n^2+24-3n
-n^2+5n+24
Let x be the number of hours and Let y be the number of views.
x y
1 125
2 250
3 375
4 500
5 625
Angle: x
complement: 90-x
3x=90-x-14
4x=76
x = 19
90-x= 71
