Answer:
Step-by-step explanation:
By the trapezoid midsegment theorem,
2x = (x-6) + (2x-8)
2x = x - 6 + 2x - 8
2x = 3x - 14
x = 14
So we know AD = 8, EF = 14, and BC = 20
Answer:
Step-by-step explanation:
8:60 is the rate
Divided by 2
4:30
So, she could run 4 kilometers in 30 minuets.
Divide by 2 again.
2:15
She can run 2 kilometers in 15 minuets.
circumference = diameter x PI
3300 *3.14 = 10,362 feet
5:3. Simply by the common factor which is 6. 30 divided by 6 is five. 18 divided by 6 is 3. Therefore the simplest form is 5:3
The answer is 81. since (-3)^2 is 9. Therefore, 9x9=81.
