The answer is 125,000 since the hundred spot has a number of five or greater on it
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)
Generally four, but polynomials may have repeated roots. “Could” contain four different binomial, but they just happen to be the same.
3x+7=4x
Move the 3x to the other side
7= 4x-3x
7=x
Take the formula of a rectangle and use substition to fill in the information you already know.
A= LxW
57f = L x 3.8f
Now use the balance method to figure out what the length is. You're really just doing algebra.
57f= L x 3.8f
57f ÷ 3.8 f = L x 3.8f <span>÷ 3.8f
</span>
15f= L
ANSWER: The length of the sidewalk in 15 feet.
CHECK:
A= L x W
A= 15f x 3.8f
A= 57 feet
