Mathematics

Irina18 [472]3 years ago
3 0

Answer:

Step-by-step explanation:

(4-5i)(3-6i) = 4*(3-6i) - 5i(3 - 6i)

= 4*3 - 4*6i - 5i*3 + 5i*6i

= 12 - 24i - 15i + 30i²

= 12 - 39i + 30 * (-1)                {i² = -1}

= 12 -30 - 39i

=  -18 - 39i

You sell instruments at a Caribbean music festival. You earn $326 by selling 12 sets of maracas, 6 sets of claves, and x
IrinaK [193]
326=12m+6c+x The reason your x does not have a number is because it is unknown so in order to solve for x you need to get rid of the 12m+6c so in order to that you can divide it on both sides so you would get 326/12m+6c=x the divide your numbers 18.1=x but you cant have a tenth of a djembe drum so you would have to round up to 19.
