When two lengths, a and b are proportional, the ratio of their volumes is a^3 = b^3. Since A = 2B, the ratio is A^3 = 8B^3
Answer:
The Attachment has the answer
Step-by-step explanation:
Answer:
B.The matrix is invertible because the determinant is defined.
Step-by-step explanation:
<u>Definition:</u> A matrix is invertible if the determinant is not equal to zero.
Given the matrix:
The determinant of the matrix:
Since the determinant, , the matrix is invertible because the determinant is defined.
X equals 9.5, when you add the 9 to the other side you get 19. When you divide 2 by 19 you get 9.5 making the solution correct.
