Answer:
Yes, this is a right triangle
Step-by-step explanation:
a² + b² = c²
65² + 72² = 97²
4225 + 5184 = 9409
9409 = 9409
Since the hypotenuse equals the 2 legs, it's a right triangle

So we can answer sorry. but if you give more info I'll try to help
Answer:
x² - 8x + 20
= x²- 2*4*x + 16 + 4
= x²- 2*4*x + 4² + 4
= (x - 4)² + 4
= (x - a)² + a, with a = 4
Hope this helps!
Answer:
<u>Kathy drove the first 9 hours of the trip and Brian drove the last 3 hours.</u>
Step-by-step explanation:
Let's review the information given to us to answer the question correctly:
Total distance of the trip = 750 miles
Time of the trip = 12 hours
Speed of Kathy = 65 mph
Speed of Brian = 55 mph
2. For what length of the time did Kathy and Brian drive?
Let's solve the problem, this way:
x = Time in hours Kathy drove
12 - x = Time in hours Brian drove
Now, let's write our equation to solve for x:
65x + 55 (12 - x) = 750
65x + 660 - 55x = 750
10x = 750 - 660
10x = 90
x = 90/10
x = 9 ⇒ 12 - x = 3
<u>Kathy drove the first 9 hours of the trip and Brian drove the last 3 hours.</u>
