Multiply [4 0] 2 -1 5 now what i am looking at is the two centers the [ and all numbers are inside the [ ] thats just how its set up. thats the only way i know how to put it.. im giving more than 10 points for the hassle.

When a matrix is multiplied by a constant, the constant multiplies each of the elements of the matrix.

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
