How would i solve simplify. -6(x-3)-4(y+5)+(-5)(7-2b) because i had it ona test and put it in wolfram alpha but for the first time i was stumpedand iwanna know step by step how to solve it the distrubtuive propery has always been a pain for me so can anyone teach me

The distributive properties applies every time you want to multiply a whole parenthesis by a number.

As the name suggests, you "distribute" the number to all terms in the parenthesis: you perform as many multiplication as many terms in the parenthesis.

So, for example, we begin with

So, we multiply -6 times both terms in the parenthesis, and sum the results:

And so on with the other terms:

Now sum all the pieces together:

110698.56 square miles

step-by-step explanation:

multiply 3.8 by 102

387.6

multiply 2.8 by 102

285.6

multiply those two to get

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
