Please help I’m so lost

u = 7.21

Step-by-step explanation:

The magnitude of u is just the distance between the two points. The coordinates of the left-most point are (-2,-8) and the coordinates of the right point are (4, -4). I'm assuming the x coordinates here because we don't actually know the scale.

Ok so from these points, you can draw a triangle (u can see it in the attached file).

From the coordinates we can tell the lengths of the sides, and the triangle shows that u is the hypotenuse of the triangle. This triangle is also a right triangle, so u can use Pythagoras' theorem to find the length of u.

Since c = u, we know now that the magnitude of u is 7.21

Hope this helps!

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480
