Answer:
Step-by-step explanation:
Karen open a credit account to purchase a new bed.
The cost of the bed = $1,000
She made a down payment of $200.
She have to pay = 1,000 - 200 = $800
Now the financial situation is Karen has a balance of $800 in her credit account which she has to pay later.
2x+6=20
2x=20-6
2x=14
x=14/2
x=7
42 cakes
10+32=42 cakes
7, -1
x^2 - 6x + 7 = 0
(x - 7)(x + 1) = 0
==> x = 7, x = -1
