Answer:
d. x = 6


Steps:
First, You square both sides to cancel the square root. Leaving -3x -2 on one side and 2x + 4 on the other.


Second, combine like terms. Subtract -2x both sides and add 2 both sides.



Third, that will give you 3x - 2x = 4 + 2. Which gives you x = 6.

Evgen [1.6K]

Assuming your interest rate on the loan is 8. 6%. The additional margin generated will cover the interest payments.

<h3>Additional margin</h3>

Let determine the weekly interest

Weekly interest= 8.6% /12 x 60,000

Weekly interest= $99.23

Let calculate the amount left since the business generates $500 at a margin of 80

Amount left= 500 x 80%

Amount left= $400

Based on the above calculation we can see that the amount of $400 is sufficient enough to cover the $99.23 payments.

Inconclusion  the additional margin generated cover the interest payments.

What is the area of the rectangle shown on the coordinate plane? enter your answer in the box. Do not round at any steps. Units²
nadya68 [22]

The area of this rectangle is 42 units.

<h3>What is the area of a polygon?</h3>

The area of a polygon refers to the total surface a polygon covers. This can include the total surface of a triangle, rectangle, octagon, etc.

<h3>How to calculate the area?</h3>

There are specific formulas to calculate the area of different polygons. In the case of rectangles the general formula is:

  • A = length x width

Moreover, because there are diagonal lines, you need to use this formula to calculate the distance of the length and width.

  • √[(x2-x1)²+(y2-y1)²

Length:

(5,2) (12 ,-5) coordinates in the plane for the upper length

  • √(5-12)²+(2- (-5)²
  • √(-7)²+(7)²
  • √49 + 49
  • 9.89

Width:

(2, -1) (5, 2) coordinates in the plane

  • √(2-5)²+(-1- 2)²
  • √(-3)²+(3)²
  • √9 + 9
  • √18
  • 4.24

4.24 x 9.89 = 41.9, which can be rounded as 42 units.
