30 inches.
When trying to find the perimeter of a rectangle, add the lengths of all of the sides. So, 5 + 5 + 10 + 10 = 30.
Answer:
16. f(y-2) = 2(y-2)²-5
= 2(y²-4y+4)-5
= 2y²-8y+8-5
= 2y²-8y+3
17. f(a+h)-f(a) = 2(a+h)²-5-(2a²-5)
= 2(a²+2ah+h²)-5-2a²+5
= 2a²+4ah+h²-2a²
= h²+4ah
Answer:
225 matchups.
Step-by-step explanation:
Use Fundamental Counting Principle.
Why? the Fundamental Counting priciple states that if one event occur n ways and another event occur p ways, then the total outcomes is n times p.
Here, there are 15 ways a team can winin each conference so we got
15 times 15 ≡225
X=2 is the answer 7(2)+3=17
