Answer:

Step-by-step explanation:

I don't think that's how those specifc diagrams work. X in this case would be 3 not seven.

Yes you can move the x and the 1s but it would break the whole diagram. It would just be an (expression/term). Not a full diagram.

You said this was 7th grade math? Wow. I learned this in 5th grade!

Answer:

He is incorrect. This is because the expression he has right now is x+2=5, making x=3. So if he adds 2 to the right then it's wrong because it would be 3=7.

Answer: Hi!

First, UxV = sin(a)*IUI*IVI

where a is the angle between U and V, in this case 45°.

First, the cross product of UxV points:

Here you can use the right hand method,

Put your hand flat, so the point of your fingers point in the same direction that the first vector, in this case U, so your fingers will point to the north.

Now roll your fingers in the direction of the second vector, so here you will roll your fingers in the northeast direction. Now you will see that your thumb is pointing down, so the cross product of UxV points down.

And the magnitude is 6*5*sin(45) = 21.213

the length of diagonal of a rectangular field is 23.7 m and one of its sides is 18.8 m. find the perimeter of the field.

katen-ka-za [31]

Answer:

Approximately 66.4 Meters

Step-by-step explanation:

So we have a rectangle with a width of 18.8 meters and a diagonal with 23.7 meters. To find the perimeter, we need to find the length first. Since a rectangle has four right angles, we can use the Pythagorean Theorem, where the diagonal is the hypotenuse.

$a^2+b^2=c^2$
