The answer is 19, C, because the 2 biggest are cat & dog, the dog is 8 and the cat is 11, 11+8=19.
5x = length
4x = width
324 = perimeter
formula: P = 2(length) + 2(width)
324 = 2(5x) + 2(4x)
324 = 10x + 8x
324 = 18x
18 = x
Substitute the value of x = 18
Length = 5x = 5(18) = 90meters
Width = 4x = 4(18) = 72meters
The function of 5 (or y when x is 5) can not be determined with this little information.
The answer I got would be 2(x+18)
Answer:
x = 10
Step-by-step explanation:
30/35 = (6x-6)/63
210x - 210 = 1890
210x = 2100
x = 10
