Answer:
The area of the rectangle is 27
Step-by-step explanation:
so we need our formula to find the area of a rectangle. Area = Width × Length
Now we plug our numbers in.
A = 9 × Length
Since we are missing our exact Length amount we need to figure that out first. The statement says the length is 1/3 the size of the Width and the Width is 9.
9 × 1/3 = 9/3
9/3 can be simplified to 3 thus our Length is 3. now we add this into our equation
A = 9 × 3
A = 27
The answer is A) -23
A is a 1x3 Matrix while B is 3x1 Matrix. Since A has the same number of rows as that of the number of columns of B, they can be multiplied. A has 1 row and B has 1 column. So, their products is a 1x1 Matrix.
Simply, the operation is:
(3)(-1) + (-2)(4) +(6)(-2) = -23
