The answer is -16 - 10i.
Using the distributive property on the first part, we have:
-2i*7--2i*4i + (3+i)(-2+2i)
-14i+8i² +(3+i)(-2+2i)
Using FOIL on the last part,
-14i+8i²+(3*-2+3*2i+i*-2+i*2i)
-14i+8i²-6+6i-2i+2i²
-10i+8i²-6+2i²
Since we know that i = -1,
-10i+8(-1)-6+2(-1)
-10i-8-6-2
-16-10i
Answer: one billion 1,000,000,000 1 x 109
ten billion 10,000,000,000 1 x 1010
one hundred billion 100,000,000,000 1 x 1011
one trillion 1,000,000,000,000 1 x 1012

So sorry if this did not help!
7k + 4 is the simplified version
Answer:
Step-by-step explanation:
Given the expression
Remove parentheses: (a)=a
Group like terms
Add similar elements
∵ 
Add similar elements
∵ 
Thus, the equivalent expression in simplified form:
122.5.
A=b x h/2. A=122.5 b=7
A x b=h
122.5 x 7 =122.5
