What is −3(2a)+−4(−6b)+5(3c) written on standard form. pls help asap​

-6a+24b+15c

Step-by-step explanation:

The given expression is :

−3(2a)+−4(−6b)+5(3c)

We need to write it in the standard form.

We know that,

-3(2) = -6, -4(-6) = 24 and 5(3) = 15

−3(2a)+−4(−6b)+5(3c) = -6a+24b+15c

Hence, the required answer is equal to "-6a+24b+15c".

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
