B)26 is the answer for the question
Next time, please list the possible answer choices. Without them, all I can do is to attempt this problem without having those choices as guidelines.
I must assume that your expression x^4-5x+3/x^2+7 actually meant:
5x + 3
x^4 - ---------------
x^2 + 7
and I assume that this result was one of the several possible answer choices.
Answer:
Step-by-step explanation:
If you have a square of side
, its diagonal would be
, and its area 
If the big square has a area of 900, this implies that its side is
, so the two diagonal of squares 2 and 4 added together would be
, therefore one diagonal wold be
. and its side
. The area (of one square) is 
finally the two areas combined (squares 2 and 4) would be 225
1) 4(8j + 9)
2) 24j + 36 + 8j
