AB=
BA=
Step-by-step explanation:
Given the matrices A= and
B=
To find the product AB and BA
AB=
Therefore the product of AB is
AB=
BA=
Therefore the product of BA is
BA=
The products of AB and BA is given by
AB=
BA=
Answer:
Length = 3 cm
Width = 1 cm
Step-by-step explanation:
Let the length of rectangle be l and width of rectangle be w.
According to problem,
l = 3w {Length of rectangle is equal to triple the width}
And Perimeter,P = 8 cm
Since, P = 2 ( l + w )
or 8 = 2( l + w)
Plug l =3w in the above perimeter equation.
We get:
8 = 2( 3w + w)
8 = 2(4w)
8 = 8w
or w = 1 cm
Then length ,l = 3w =3 * 1 = 3 cm
Hence length of rectangle is 3cm and width of rectangle is 1cm.
Answer:
Choice A, x=1
Step-by-step explanation:
So, to start, there's two routes that you can take there. I am going to show one of these routes.
Within the image, you see two triangles, you are able to tell that these triangles share two of the same sides, because of congruency lines on each of them.
The first group of congruent sides have 1 line going through them, the second group has 2 lines going through them. Let's go with the first group.
With the first group, we are using the lines CB and FE, where the measurements on each of them are 3x+1 and x+3 respectively.
Since they are congruent, they are equal and we can just set them equal to each other.
Starting With:
3x+1 = x+3
Step 1) Cancel out the +1
3x+1 -1 = x+3 -1
3x = x+2
Step 2) Cancel out the x
3x -x = x+2 -x
2x = 2
Step 3) Divide by 2 get x by itself
2x/2 = 2/2
x=1
All done!
Answer:
$82,250 < x <= $171,550
Step-by-step explanation:
You didn't provide all the possible answers. In this case we don't need to see all answers to help you... but because you didn't provide all the choices for answer, we can't give the exact answer, only the possible range of values.
The question asks for a possible taxable income for someone filing under the 28% bracket.
If we look at the table, we see the 28% bracket is for income ranging from $82,250 (exclusively) to $171,550 (inclusively)
So, your answer has to be within the range:
$82,250 < x <= $171,550
It cannot be $82,250 but it can be $171,550 and any number in between.
Since you didn't provide all the answer choices, we can't tell you if it's B, C, D, and so on... but we can tell you it's not A.
