Answer: Part one! --- y=x^2+12x+27

Part two --- y=x^2+18x+80

Step-by-step explanation: For both of these questions, you have to work backwards to find the factors from the roots, then multiply the factors together! I know it looks like a long process, but really it's just turn around, back up, multiply and BOOM! Answer is there for. You just have to look at your signs, exponents and make sure you keep PEMDAS in order as well. All math basically requires PEMDAS. Like these questions right here that you asked! ☺

It's pretty easy but it takes a while to get a hang of it. I am still trying to get better at it as well but I am also trying to help you out!

I hope I helped you! Again! Haha! ☺

Paul has 12 coins in his pocket, consisting entirely of dimes and quarters. If he has a total of 195 cents in coins, how many co
anyanavicka [17]

Let x be the number of dimes

and y be the number of quarters

Total number of coins = 12

So number of dimes + number of quarters = total number of coins

x + y = 12 ---------> equation 1

We know, 1 Quarter = 25 cents, 1 Dime = 10 cents, total cents = 196

y quarters = 25y cents , x dimes = 10x cents

x dimes + y quarters = 195 cents

10x + 25y = 195 -----------> equation 2

Now solve both equations

x + y =12, we solve for y by subtracting x on both sides

y = 12-x

Now substitute y in second equation

10x + 25(12-x) = 195

10x + 300 -25x = 195 (combine like terms)

-15x + 300 = 195 (subtract 300 on both sides)

-15x = -105 ( divide by -15)

x=7

y= 12-x

y=12-7 = 5

The number of dimes = 7

Number of quarters = 5
