Answer:
15401.175 metros
Step-by-step explanation:
El corredor Belga tenía 365 maratones que a razón de 42.195 metros son:
365 * 42.195 = 15401.175 metros
So first you want to do the multiplication.
(3-4i)*(1+5i)
So what you want to do is multiply everything inside the parenthesis by everything inside the other parenthesis.
Or,
3 * 1 + 3 * 5i + -4i * 1 + (-4i) * 5i
Or,
3 + 15i + -4i - 20i
Then,
3 + -9i
3 - 9i - (2 - i)
Open the parenthesis, and since it has a minus before it reverse the operator inside of the parenthesis.
3 - 9i - 2 + i
Or,
1 - 8i
Answer:
<h2>( 7a - 2b ) ( 3x - 5y )</h2>
<u>Step-by-step explanation:</u>
21ax + 10by - 35ay - 6bx
21ax - 35ay - 6bx + 10by
7a ( 3x - 5y ) - 2b ( 3x - 5y )
( 7a - 2b ) ( 3x - 5y )
