There are 7 numbers

Calculate sum of digits of all numbers

331=3+3+1=7
482=4+8+2=14
551=5+5+1=11
263=2+6+3=11
383=3+8+3=14
362=3+6+2=11
284=2+8+4=14

We observe that

$\\ \sf\longmapsto 482\sim383\sim284$

$\\ \sf\longmapsto 551\sim263\sim362$

331 is odd one

Use the distributive property to expand the expression. −2(5a − 3b2) − 4b + 3 A) −10a + 6b2 − 4b + 3 B) −10a − 6b2 − 4b + 3 C) −

Nikolay [14]

The answer is: [B]: " -10a + 6b² − 4b + 3 " .
_____________________________________
Explanation:
____________________
Given:
____________________________
-2(5a − 3b²) − 4b + 3 ;
_________________________________
"Use the distributive property [of multiplication] to expand the expression."
______________________________________________
Note the distributive property of multiplication:
______________________________________________
a(b + c) = ab + ac ;
a(b − c) = ab − ac ;
______________________________________________
So, we have: " -2(5a − 3b²) − 4b + 3 " ;
______________________________________________

Start with: " -2(5a − 3b²) " ;
______________________________________________

-2(5a − 3b²) = (-2*5a) − (-2*3b²) = (-10a) − (-6b²)

= -10a + 6b²
________________________________________________
→ Now, bring down the rest of the problem;
________________________________________________
-10a + 6b² − 4b + 3 ; which is: Answer choice: [B].
