Answer:

3.14 cm

Step-by-step explanation:

∆DEG is similar to ∆DFH, so

DE/DG = DF/DH

3.0/2.3 = (3.0 + 4.1)/(2.3 + x)

3.0/2.3 = 7.1/(2.3 + x) Divide each side by 7.1

2.3/3.0 = (2.3 + x)/7.1 Multiply each side by 7.1

(2.3 × 7.1)/3.0 = 2.3 + x Subtract 2.3 from each side

x = (2.3 ×7.1)/3.0 – 2.3

= 5.443 – 3.0

= 3.14 cm

<em>Check: </em>

3.0/2.3 = (3.0 + 4.1)/(2.3 + 3.14)

1.304 = 7.1 /5.44

1.304 = 1.305

The numbers check to the nearest hundredth.

The answer is the third one (C?) because if you started at 0, you are going below it since you are losing yards, causing you to have less and less yards. Adding two negatives gives you a lesser amount.
