What is the product?<br> 3 x [1 -4 5 -7]
Roman55 [17]

This looks like scalar matrix multiplication. The idea here is to multiply the scalar 3 by each item inside the matrix.

Doing so leads to the answer [3   -12    15    -21]

Side note: I'm assuming the matrix given to you has 1 row and 4 columns.

What is the difference between d and 7?
Goryan [66]

Answer:

d - 7

Step-by-step explanation:

The word "difference" tells us that we will be using subtraction. Also, subtraction is not the same if you reverse the terms like, x - 2 and 2 - x are not the same. In your question it say "d and 7" so that's the order we use in the algebraic expression.
