Answer:
=53
Step-by-step explanation:
a=5-b &. a=9+b
combine
5-b=9+b
-4=2b
b= -2
thus, a=7
(-2)^2 + (7)^2
4+49
=53
Marsh Trail is longer than Woodland trail by 2.5 miles
Step-by-step explanation:
A town park has 2 biking trails
1. Marsh Trail is 5 and three over ten miles long
2. Woodland trail is 2 and 4 over 5 miles long
We need to find that Marsh Trail is how much longer than
Woodland trail
To do that we will subtract the length of the Woodland trail from the
length of the Marsh Trail
∵ The length of Marsh Trail is 5 and three over ten miles
- 5 and three over ten = 
∵
= 0.3
∴
= 5.3 miles
∵ The length of Woodland trail is 2 and 4 over 5 miles
- 2 and 4 over 5 = 
∵
= 0.8
∴
= 2.8
∴ The difference = 5.3 - 2.8
∴ The difference = 2.5 miles
Marsh Trail is longer than Woodland trail by 2.5 miles

Step-by-step explanation:
The measure of angle IMJ is 62.5 degrees
<h3>How to solve for IMJ?</h3>
To solve for angle IMJ, we make use of the following arc intercept theorem.
Angle IMJ = 0.5 * (Arc IJ + Arc LK)
So, we have:
Angle IMJ = 0.5 * (40 + 85)
Evaluate the product
Angle IMJ =62.5
Hence, the measure of angle IMJ is 62.5 degrees
