Answer:
In group A, they have at least one 90 degree angle. In Group B, they do not have any 90 degree angles.
Answer:
<em>u</em> = 7.21
Step-by-step explanation:
The magnitude of <em>u</em> 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 <em>u</em> is the hypotenuse of the triangle. This triangle is also a right triangle, so u can use Pythagoras' theorem to find the length of <em>u</em>.

Since c = <em>u</em>, we know now that the magnitude of <em>u</em> is 7.21

Answer:
Mix numbers: 11 2/5
Improper numbers: 57/5
Step-by-step explanation:
4/10 in 11 4/10 can be simplified into 2/5
Also, mixed numbers and improper fractions are the simplest forms
Thus the answer has two solutions, with the same value:
11 2/5 or 57/5
hope this helps!
Add 20 both sides
15x<150
divide bothsides by 15
x<10
ok
