Answer:
A = 1/2bh
Step-by-step explanation:
40 = (.5)(6x - 4)(x)
40 = (3x-2)(x)
40= 3x^2 - 2x
3x^2 -2x - 40 =0
3x^2 - 12x + 10x - 40 = 0
3x(x - 4) + 10(x -4) = 0
(3x + 10)(x - 4) = 0
x = {4 , - 10/3}
x = 4 , b = 20. h = 4
Answer:
2x-3y=20
12x+8y=-192
Solution
In the determinant of the matrix to find the variable "x" [Ax], we replace the coefficients of "x" (2 and 12) by the independent terms (20 and -192 respectively).
In the determinant of the matrix to find the variable "y" [Ay], we replace the coefficients of "y" (-3 and 8) by the independent terms (20 and -192 respectively).

-hope this helped-
C)5.40
The answer is $5.40 because 5 x 8=40 and the sales tax is 8% so you just add 2 decimal places so 5.00 + .40 =5.40.
P.S. You put the answer in your question.
