Answer:
17x^2+31x+3
Step-by-step explanation:
Answer:
a) 0.8( 8/10 gives 0.8)
b)0.7( if it was 7/100 it would have been
0.07)
c)3.5( by converting mixed fractions to improper fractions, that is, 3×2+1 and having the same denominator 2… we get 7/2… for the purpose of converting it to decimal, 7×5/2*5= 35/10… by moving one decimal place to the left, we get 3.5)
D) 2.5 ( the same way as c) 5*5/2*5: 25/10 or you can make it to be 5*50/2*50: 250/100 which still gives 2.5)
This is the answer I got according to the app called “Math”
13 + 3i
15 - 6i - 2 + 9i → Sum
collect like terms
(15 - 2) + ( - 6i + 9i) =13 + 3i
