Step-by-step explanation:
Replace n with the given value, 1/4
9 (1/4 + 2) - 5×1/4
9×9/4 - 5/4 Do inside the parenthesis
81/4 - 5/4 add the terms
76/4 = 19 this i.s the result
Answer:
19
9(n+2)-5n for n = 1/4
Solve :
9(n+2)-5n
Put value of n
= 9(1/4 + 2) - 5 (1/4)
= 9( (1+8)/ 4 ) - 5/4
= 81 /4 - 5/4
= 81-5/4
= 76/4
= 19
