Answer:
Step-by-step explanation:
First you would take out 15 negative tiles.
Then you would separate each the tiles into 3 groups evenly.
In the end you should have 5 tiles in each of the 3 groups.
hope this helps:)
10+8=5x+3x
18=8x
X=2,25
Hope it’s right
Answer:
42.1 degrees
Step-by-step explanation:
- since we have a opposite/hypotenuse ratio, that means we used sin x = o/h
- this means, sin x = 0.67
so, x = 
(0.67) {sin inverse}
x = 42.06 degrees, i rounded it up to 42.1 but its up to you (or according to the question)
Answer:
Option c.
Step-by-step explanation:
The set of points (x, y, z) such that z = 6.
So, all pairs are in the form of (x,y,6).
where, x and y can be any real number.
It the set of points (x,y,6), z-coordinate is constant.
So, it represents a plane parallel to xy-plane and the distance of this plane from the xy-plane is 6 units.
Therefore, the correct option is c.
Answer:
(5-2z)(5+2z)
Step-by-step explanation:
25 -4z^2
Rewriting
5^2 - (2z)^2
This is the difference of squares a^2 - b^2 = (a-b)(a+b)
(5-2z)(5+2z)
