PLZZ HELP Explain how to MULTIPLY these two imaginary numbers, together. Use complete English and math sentences.
(3i) ( 4i)

2. Explain the steps to add these Polynomials.
( 3x2 + 4x +5 ) + ( 2x2 +3x + 7)

answer: what are the following choices

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
