Perimeter = 2(width) + 2(length)
w = 5x
l = x + 5
P = 2(5x) + 2(x + 5)
P = 10x + 2x + 10
P = 12x + 10
Answer:
n-2
Step-by-step explanation:
1. Find what has been done to the input value to give the output value. Here, we can see that each input value is two more than each output value, so two has been subtracted from each input value to give the output. This means that the rule for this function is: <em>take the input value and subtract two.</em>
2. Express this in terms of n. We can then express this in terms of n (using n to show the rule that we have found). Since n is the input value we have, to find the output when the input is n, we subtract two from n. This gives us our answer of n-2.
(3a) - (8a) = -5a
2b + b = 3b
-5a + 3b
All you would have to do is substitute!
Answer:
First one will be 2
Second one will be 10
Third one will be undefined
Explanation:
So for the first one you are substituting x for -3 so then the equation would look like this: -3^2+9/-3^2, this will equal to 9+9/9 which your answer would be 2 since 18/9 is 2. For the second one it will look like this -1^2+9/-1^2 which would be 1+9/1, this would equal to 10. For the last one it will look like this 0^2+9/0^2 which would just be 0+9/0 9/0 would be undefined.
