U=9i-9j and v=-8i 4j find u-v

u - v = 17i  -13j

Step-by-step explanation:

Rewrite u=9i-9j and v=-8i 4j  vertically:

u=9i-9j

v=-8i + 4j

We want to subtract the second equation from the first:

u=9i-9j

v=-8i + 4j

u - v = 17i  -13j

Note:  I assumed that a " + " sign precedes 4j in the second equation.

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
