Answer:

Please check the explanation.

Step-by-step explanation:

Considering the expression

9i+2\left(7+3i\right)

  • Applying the distributive law

        a\left(b+c\right)=ab+ac

so the expression becomes

=9i+2\cdot \:\:\:7+2\cdot \:\:\:3i

Group like terms

=9i+14+6i

Add similar elements: 9i+6i=15i

=15i+14

Answer:

First one is 41

Second one is 87

Step-by-step explanation:

The unshaded part will be 16*8 then subtracts the shaded part which is 41.  Then you get the answer 87.
