What were the dimensions of the original photo?

never [62]

Answer:

11 inches by 11 inches

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

Given the information:

The area of the reduced photo is 64 square inches
The equation $(x-3)^{2}$ = 64 where x is the the side measure of the original photo.

Let us solve for x by taking positive square root of both sides.\

$\sqrt{(x-3)^2}=\sqrt{64}\\\sqrt{(x-3)^2}=\sqrt{8^2}\\x-3=8$

<=> x = 11

So the dimensions of the original photo is 11 inches by 11 inches

We choose A

Hope it will find you well.

Whats the next two terms in order are p+q, p , p-q

Law Incorporation [45]

Answer:

p - 2q and p - 3q

Step-by-step explanation:

A Series is given to us and we need to find the next two terms of the series . The given series to us is ,

$\rm\implies Series = p+q , p , p - q$

Note that when we subtract the consecutive terms we get the common difference as "-q" .

$\rm\implies Common\ Difference = p - (p + q )= p - p - q =\boxed{\rm q}$

Therefore the series is Arithmetic Series .

Arithmetic Series:- The series in which a common number is added to obtain the next term of series .

And here the Common difference is -q .

Fourth term :-

$\rm\implies 4th \ term = p - q - q = \boxed{\blue{\rm p - 2q}}$

Fifth term :-

$\rm\implies 4th \ term = p - 2q - q = \boxed{\blue{\rm p - 3q}}$

Therefore the next two terms are ( p - 2q) and ( p - 3q ) .
