3 yards/3 walls = 1 yard per wall
Area = Length * Width
Area = 1 * 1 = 1 square yard
Answer:
det(A) = (-6)(-2) - (-4)(-7)
Step-by-step explanation:
The determinat of the following matrix:
![\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Da%26b%5C%5Cc%26d%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Is given by: Determinant a*d - b*c
In this case, a=-6, b=-7, c=-4 and d=-2.
Therefore the determinant is: (-6)(-2) - (-7)(-4).
Therefore, the correct option is the third one:
det(A) = (-6)(-2) - (-4)(-7)
Y= 2x+10 would be the equation and it would have no solution because there's no value if x nor y
B.) four hundred ninety-eight, You would add the number of mistakes in the barrels, then subtract that from five hundred.
Answer:
tip: $7.50
total: $57.50
Step-by-step explanation:
you change the 15% into a decimal by moving the the decimal point 2 spots to the left so now you have .15
next do .15 * 50 to get 7.5, which is the tip
now to find the total, add 7.5 + 50 to get 57.5
