We can say that because 3 times 9, which would equal 27, could be the same as 4*9, which would be 36. So Pat needs 36 pints of green paint. Down below is a tape diagram so you can see what it is.

Answer:
The matrix is not invertible.
Step-by-step explanation:
We are given the following matrix in the question:
Condition for invertible matrix:
A matrix is invertible if and only if the the determinant is non-zero.
We can find the determinant of the matrix as:
Since the determinant of the given matrix is zero, the given matrix is not invertible.
Answer:
Step-by-step explanation:
Given that L is a line parametrized by
The plane perpendicular to the line will have normal as this line and hence direction ratios of normal would be coefficient of t in x,y,z
i.e. (2,3,-1)
So equation of the plane would be of the form
Use the fact that the plane passes through (2,0,-1) and hence this point will satisfy this equation.
So equation is
b) Substitute general point of L in the plane to find the intersecting point
i.e. same point given.
