26 Square Inches.
If you find the area of the two missing fragments, which are 3 in. by 4 in., you can make the equation 2(3 x 4)= 24. Find the area of the whole 5 in. by 10 in. which is equal to 50 in. Subtract 24 from 50 and you get 26.
Answer:
x 1 2 6 12 25
f(x) 22 34 82 154 310
f(3)= 46 means that in the third month, the online magazine provider will charge a total of $46.00
Step-by-step explanation:
For finding the missing f(x) values:
Plug in the x-values that are given into the original equation: f(x)= 12x + 10
ex: f(1)= 12(1) + 10 => 22
For finding the missing x value, set the original equation to the given f(x) value
ex: 34 = 12x + 10 => 2
Answer:
66.67%
Step-by-step explanation:

Rule: The sum of any integer and its opposite is equal to zero. Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.
