The answer is 8000 meters I think
Alright. So the problem is
10*12+-15/5+2(9-4)
Lets break down what we can for now
First focus on parenthesized, multiplying, and dividing in the problem.
10*12=120 15/5=3 (9-4)=5
120+-3+2*5
So the next step, we see 2*5 and a negative -3 on top of a positive symbol.
2*5=10
120-3+10
Now subtract from the left to the right and get your answer.
120-3=117
117+10=127
<span>(4 - 8i)(2 - 7i)
Use the method FOIL
8 - 28i - 16i + 56i^2
Subtract 16i from -28i
Final Answer: 8 - 44i + 56i^2</span>
What you need to do is divide the fraction then multiply by the reciprocal of that fraction
So it’ll be 9-3x3+1
Then you multiply the numbers
9-9+1
Eliminate both 9’s, therefore the answer will be 1
