Is the question asking by completing the square? 
X^2+2X+3=0
X^2+2x+1+2=0
(x+1)^2+2=0
(x+1)^2=-2
x+1=squr root 2i or x+1=-sqr root 2i

Describe two different ways that you could find the product 8 x 997 using mental math. Find the product and explain why your met
jolli1 [7]
One method is to round 997 up to 1000, multiply by 8, and then subtract 8 times 3. This would give you the solution of 7976.

Another method (Which I personally wouldn't use) is to recursively double 997. This is more difficult, although effective. After you double 997, double the resulting number, and then double the resulting number from that, you have the solution. This is because 2^3 is 8.

Tommy purchased a riding lawnmower with an original value of $2,500. If the value of the riding lawnmower decreases by $300 per
Eva8 [605]

Answer:

$1000.

Step-by-step explanation:

Let x represent number of years.

We have been given that Tommy purchased a riding lawnmower with an original value of $2,500. The value of the riding lawnmower decreases by $300 per year. We are asked to find the value of lawnmower after 5 years.

Since the value of the riding lawnmower decreases by $300 per year, so value of lawnmower decrease in 5 years would be 5 times $300.

The final value of lawnmower would be initial value minus value decreased in 5 years.

\text{The value of the lawnmower after five years}=\$2500-\$300(5)

\text{The value of the lawnmower after five years}=\$2500-\$1500

\text{The value of the lawnmower after five years}=\$1000

Therefore, the value of lawnmower after  years would be $1000.
