Answer:
The missing side length is 6.
Step-by-step explanation:
Because the two triangles are similar,
the following equation of ratios is true:
m 4
----- = -----
15 10
Cross-multiplying, we get:
10m = 60, or m = 60/10 = 6
The missing side length is 6.
Since you know that DA and DC are equal in length, you can say 2x-3=x+2, when you add 3 to both sides, it becomes 2x=x+5, subtract x from both sides, and you find that x=5
A
2,000×(1+0.085×10)
=3,700
B
2,000×(1+0.08)^(10)
=4,317.85
Bank B is the better investment. In 10 years, her $2,000 will grow to $4,317.85, and with bank A, her $2,000 will grow to $3,700
