The common difference is the constant that you get when you get the difference between any term and the one preceding it. In this case:

(3--4)=(10-3)=(17-10)=d=7

BRAINLY!!!- if a=7, b=8, and c=9.2 is this a right triangle? why?

Travka [436]

Answer:

Step-by-step explanation:

If this were a right triangle we would assume the Pythagorean Theorem to prove it

$a^{2} +b^{2} =c^{2}$

$7^{2} +8^{2} =9.2^{2}$

this gives us

49+64=84.64

this is 143=84.64 and therefore not equal and not a right triangle

Chandra will have 55 baseball cards

Step-by-step explanation:

Total baseball cards = 152

Let

Chandra's collection = p

Chandra has 42 baseball cards less than Simon so Simon will have 42 cards more:

Simon's Collection = p+42

We need to find Chandra's collection.

Total baseball cards will be 152 so, the equation will be:

$p+(p-42)=152$

Solving and finding value of p (Chandra's card)

$p+p-42=152\\2p=152+42\\2p=110\\p=110/2\\p=55$

So, Chandra will have 55 baseball cards.
