16b +5c -10 -8c +2b
18b - 3c -10
Answer:
110°
Step-by-step explanation:
Angles on a quadrilateral always add up to 360°.
So, 100+95+55 = 250.
360-250 = 110°
Answer:
2nd option is the correct one
log|x|-f(x)+k
Answer:
<h2>320</h2>
Step-by-step explanation:
Let the unknown number be x

Cross Multiply

Divide both sides of the equation by 75

Simplify

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
Hope this helps!
