The matrix r=12/4 represents the length of 12 in. and the width of 4 in. of a rectangle. if matrix multiplication is used to double the length and width of the rectangle which represents the result of the matrix multiplication

Hence, in matrix from it could be written as:

R'=24/8=[24,8]

Step-by-step explanation:

It is given that:

The matrix R=12/4 i.e. R=[12,4] represents the length of 12 in. And the width of 4 in. of a rectangle.

If matrix multiplication is used to double the length and width of the rectangle.

i.e. the length of rectangle will get doubled so that the length will be=12×2=24 inches.

and similarly the width of the rectangle will get doubled and hence width of rectangle will be=4×2=8 inches.

Hence, in matrix from it could be written as:

R'=24/8=[24,8]

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
