Answer:
Step-by-step explanation:
To find the value of x, Cramer's rule says you replace the x-coefficients with the equation constants to form the matrix whose determinant is the numerator of the fraction. The denominator is the determinant of the matrix of coefficients. The equation constants are 148 and 246, so you expect to find those in the first column of the numerator (answer choices A and C).
The calculation is carried out correctly only in answer choice A.
Answer: $171.31
<u>Step-by-step explanation:</u>
A = P(1 - r)ⁿ
Given: P = 200, r = 1.1% (.011), n = 14
A = 200(1 - .011)¹⁴
= 200(.989)¹⁴
= 171.308
Since we are talking about money, round to two decimal places.

Answer: The width is 12 feet shorter than the length.
Step-by-step explanation:
The area of a rectangle can be calculated with this formula:
Where "l" is the lenght and "w" is the width of the rectangle.
We know that lenght of Jennie's yard is 30 feet, the width is and the area is 540 square feet. Then:
Substitute these values into the formula and then solve for "x":
Therefore, the width is 12 feet shorter than the length.
