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.

Definitely not B. Just took the test

Step-by-step explanation:

Attachment.

your answer would be 10x - 1

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
