Matrix P has a dimensions of 3 X 4 and Matrix Q has the dimensions 4 X 5. Determine the dimensions of the matrix PQ if it is possible. Explain why if it is not.
Group of answer choices

Matrix PQ would have the dimensions 3 X 4

Matrix PQ would have the dimensions 4 X 5

Matrix PQ would have the dimensions 3 X 5

These matrices can not be multiplied because their dimension don't align.

  Matrix PQ would have the dimensions 3 X 5

Step-by-step explanation:

In order for a matrix product to be possible, the column dimension of the left factor must match the row dimension of the right factor. The resulting product will have the number of rows of the left factor and the number of columns of the right factor.

The product of a 3×4 matrix and a 4×5 matrix will have dimensions 3×5.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
