If a car company makes a car with the option of 4 exterior colors, 3 interior colors, and 2 engines, how can the multiplication
ivolga24 [154]

Answer:

24 !

Step-by-step explanation:

I can be wrong... but if I remember correctly, by multiplying all three numbers together and getting 24 possible variations, you're taking a shortcut of just matching, for example... one color with three diff interiors and 2 diff engines, one at a time... Whether you do it long-hand like that or just multiply the numbers altogether, you still get the same number of variations.  It's just a quicker method to solve this

4*3*2=24

hope i helped :) !

The circle below is centered at the point (-3/4) and has a radius of length 3 what is its equation??
Agata [3.3K]
{x-(-3/4)}^2=3^2
(x+3/4)^2=9
{(4x+3)/4}^2=9
(4x+3)^2/16=9
(4x+3)^2=9*16
16x^2+2*4x*3+3^2=144
16x^2+24x+9=144
16x^2+24x+9-144=0
16x^2+24x-135=0

When planning a party you want to know whom to invite. Among the people you would like to invite are three touchy friends.You kn
harkovskaia [24]

Answer:

Jasmine only.

Jasmine and Kanti only.

No one.

Step-by-step explanation:

There is no possible way to invite all three friends.

Since both Samir and Kanti will not attend if someone else is not invited, Jasmine is the only friend that can be invited on her own:

One person: Jasmine.

When inviting two people, if Jasmine is invited, Samir can't be invited and Kanti will only attend if Jasmine also does. Therefore, Jasmine and Kanti can go together and there is no way Kanti can be invited.

Two people: Jasmine and Kanti.

Furthermore, if nobody is invited, no one will be unhappy.
