X^2 + 6x = -2 is a quadratic equation that can be solved by completing the square.

x^2 + 6x + (6/2)^2 - (6/2)^2 = -2

Rewriting this, (x+3)^2 = -2 + (6/2)^2 = -2 + 9 = 7

tAKING THE sqrt f both sides, we get x+3 = plus or minus 5.

Finally, x = -3 plus or minus 5, which boils down to x=2 and x= -8.

Annabeth has $29.00 to spend at the sporting goods store.

Hi there!

I believe your answer is:

The soccer ball.

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Solving for 'c'...}}\\\\15.32 + c = 29.00\\-----------\\\rightarrow 15.32 - 15.32 = 29.00 - 15.32\\\\\rightarrow \boxed{13.68}$

⸻⸻⸻⸻

She would have $13.68 dollars left. Her second item should be the soccer ball.

Hope this helps you. I apologize if it’s incorrect.

What is the total cost of an easy-access loan of $1700 borrowed for 30 days with a 29% monthly fee?

VikaD [51]

You should find the interest (29% equals to 29/100)
29% X1700=493
So you have to pay $493 on top of $1700
total : 1700+493=2193
