Answer:
because coins are more portable
Step-by-step explanation:
-5b
is the the answer
- b - 4b = - 5b
Answer: 2 < x < 16
The triangle inequality theorem says that if we have a triangle with sides a,b,c then
b-a < c < b+a
with b being longer than 'a'
In this case, a = 7 and b = 9 and c = x
so we have
b-a < c < b+a
9-7 < c < 9+7 .... replace a with 7, replace b with 9
2 < c < 16
2 < x < 16 .... replace c with x
So x can be any number between 2 and 16. The value of x cannot be equal to 2. Also, x cannot be equal to 16 either.
The answer is 64+8y+y².
In a perfect square trinomial, you can divide the value of b by 2 and square it, and it will equal the value of c. This works in every other trinomial listed except this one:
8/2 = 4; 4²=16≠64.
-1 3 5 8 13 It is because x is grows by the number you put in and you add the 5
