Answer:
Step-by-step explanation:
To add these vectors together, we have to "glue" them together.
Let's call the vector with the length of 2 <em>A </em>and the one with length 4 <em>B.</em>
Imagine you can grab vector A with your hands and move it to the end of B (it would look like the image that's annexed)
Now imagine that we made a triangle from that, what we want to know is the hypotenuse of that triangle!
We know that when we want to find the hypotenuse of a triangle, we can use Pythagoras theorem:
Let's plug in the known values (the length of the vectors) and solve this
Good luck!
Answer:
Width: 32 inches.
Length: 64 inches.
Step-by-step explanation:
Let's say that the width of the rectangle is x inches, so the length is 2x inches.
If 2x + 4 and x - 1, the perimeter is 198 inches. That means that two times the width plus two times the length is 198 inches.
2(2x + 4) + 2(x - 1) = 198
4x + 8 + 2x - 2 = 198
6x + 6 = 198
x + 1 = 33
x = 32.
That means that the width of the original rectangle is 32 inches, and the length is 32 * 2 = 64 inches.

Answer:
Step-by-step explanation:
We can substitute the given values of , , and to find the value of this expression.
We know that <em>two negatives make a positive. </em>This means that will be the same this as
Adding a negative is the same as subtracting a positive.
