yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.

if the distance from d to d' is 10 and the distance from a to d is 2, what is the scale factor

multiply by the conjugate

the conjugate is the bottom express (6-√13) with the middle changed to +

or (6+√13)

so times it be   (6+√13)/(6+√13)
