Answer:
it is not a function because the input 5 (x) has more than one output (y)
domain (5,-1,8)
range (2,6,-2,3)

Answer:
B. 48x - 56
Step-by-step explanation:
![8(6x - 7) \\ = 8 \times 6x - 8 \times 7 \\ = 48x - 56](https://tex.z-dn.net/?f=8%286x%20-%207%29%20%5C%5C%20%20%3D%208%20%5Ctimes%206x%20-%208%20%5Ctimes%207%20%5C%5C%20%20%3D%2048x%20-%2056)
So, we know the perimeter is 24 cm. and the top part is the left part, (x) + 2, but remember, we need to have it be a number that, multiplied by 2, is 24. So, using this formula, the length, (top / bottom) is 7, and x = 5. Because 5 + 5 = 10, and when length is +2, it adds up to 14. 10 + 14 = 24. So, length is 7, width, (left, right) is 5.
