If the two lengths are 7 and 3, then I believe the length of the hypotenuse would be approximately 7.62.
Answer:
x(x + 4) = 21
Step-by-step explanation:
Area = length * width.
21 = x + 4 * x
x(x + 4) = 21
14:16 21:24 28:32 are three ratios that are equivalent
5(2x - 4) = 45
10x - 20 = 45
10x = 45 + 20
10x = 65
x = 65/10 reduces to 13/2 or 6 1/2
