Answer:
17
Step-by-step explanation:
3^2+4^2-(4x2)
9+16-8
=17
The difference between them is 2, so let the unknown numbers be x and (x+2).
<span>Their sum is 52, so: </span>
<span>52 = x + (x+2) </span>
<span>52 = x + x + 2 </span>
<span>50 = x + x </span>
<span>50 = 2x </span>
<span>25 = x </span>
<span>So your unknown numbers x and (x+2) are 25 and 27.</span>
10xy+2y+8x+7
Explanation
3xy + 4xy + 3xy = 10xy
The others cant be simplified so
10xy + 2y + 8x + 7
