If you would like to solve the equation 2 * x^2 + 8 * x = x^2 - 16, you can calculate this using the following steps:
<span>2 * x^2 + 8 * x = x^2 - 16
</span><span>2 * x^2 - x^2 + 8 * x + 16 = 0
</span>x^2 + 8 * x + 16 = 0
(x + 4) * (x + 4) = 0
x = - 4
The correct result would be x = - 4.
$639.20
She earns $5 an hour plus 4%
4% of 12,480 is $499.20
$5*28 hours is $140
$499.20 + $140 = $639.20
5000 = 5 * 10 * 10 * 10
5000 = 5 * 10^3 <<<<< answer
This can also be done as
5^4 * 2^3
Answer:
4.25 yards
Step-by-step explanation:
Area of rectangle = Base x Height
or
Height = Area of Rectangle ÷ Base
In this case, Area =38.25 sq yards and Base = 9 yards
Height = 38.25 ÷ 9 = 4.25 yards
