Well what’s the table of values ?
Answer:
12.3 inches
Step-by-step explanation:
The perimeter is the sum of the lengths if the sides therefore the perimeter P is
P=2*3+2.1+4.1= 12.3 inches
The answer is multiply abc and that’s how you get your answer
Answer:
C
Step-by-step explanation:
The inverse of a matrix is the transpose of the cofactor matrix, divided by the determinant. The determinant is (4)(3) -(1)(-5) = 17, eliminating choice B.
In a 2×2 matrix, the transpose of the cofactor matrix swaps the diagonal elements, and negates the off-diagonal elements. That is, the transpose of the cofactor matrix will look like the matrix of B. When that is divided by 17, you get the matrix of answer choice C.
