Answer:
x = ±3
Step-by-step explanation:
x^2 +3 = 12
Subtract 3 from each side
x^2 +3-3 = 12-3
x^2 = 9
Take the square root of each side
sqrt(x^2) =±sqrt(9)
x = ±3
Luci cuts a board that is 3/4 yard long into pieces that are
3/8. The pieces she cut can be solve by dividing the board by length of the new

yards which is equal to 2 pieces.
Answer:
$40.4
Step-by-step explanation:
The regular price of the fishing rod is $97
There is a 60% discount from that price.
The discount is equal to 60% of $97 which is equal to .60 * $97 which is equal to $58.2
Discount is like a markdown, so subtract $58.2 from the price of the item before the change to get $97 - $58.2 = $38.8
This is the price of the item before tax is applied.
Now you apply the sales tax of 4%.
4% of $38.8 is equal to .04 * $38.8 which is equal to $1.552
Tax is like a markup, so add $1.552 to the price of the item before tax was applied to get a selling price of $38.8 + $1.552 which is equal to $40.352
Round it up and the answer is $40.4
A rectangle has four sides, two equal to the width and two equal to the length. So, the perimeter is
If we know that the width is 5, and the perimeter is 125, we have
In your case, the unkown is called x, but the concept is the same:
where x is the length of the rectangle.
