Answer:
(c) 4x - 7
Step-by-step explanation:
7x - 3x
= -4x
-5 -2
= -7
4x - 7
5 would be the digit in the tenths place
In the ratio, the numbers are 2 for the shortest side, 3 for the middle sized side, and 4 for the longest side.
2 is to 6 cm as 4 is to x
2/6 = 4/x
2x = 4 * 6
2x = 24
x = 12
Answer: The longest side measures 12 cm.
