A=-2(negative 2) b=3 and c=5 what is 3ac-a+2b.With explanation
1 answer:
Step-by-step explanation:
a = -2
b = 3
c = 5
<h2>Question:</h2>= Solution,
= 3 ( - 2 ) × 5 - ( - 2 ) + 2 × 3
here ... ( + ) × ( - ) = ( - )
= - 6 × 5 - ( - 2 ) + 2 × 3
here .... ( - ) × ( - ) = ( + )
= - 6 × 5 + 2 + 2 × 3
= - 30 + 2 + 6
= - 30 + 8
here the ( - ) have greater variable so...
= - 22
