The rules about opositive and negative numbers include
- Two like signs become a positive sign
- Two unlike signs become a negative sign
<h3>How to illustrate the information?</h3>
It should be noted that two like signs become a positive sign. For example, (-2) × (-4) will be:
= (-2) × (-4).
= +8
Two unlike signs become a negative sign. This will be:
(-2) × (+4)
= -8

Answer: a) 
b)√131.
Step-by-step explanation:
Since we have given that
A(1,0,-5), is rewritten in vector form is given by
B(5,-3,6) is rewritten in vector form is given by
a. What is the component form of AB?
So, it becomes,
b. What is the magnitude of AB?
Hence, a) b)√131.
Answer:
W=2cm
Step-by-step explanation:
The area of a rectangle is 20 cm, with the length being 8 more than the width, two common factors to 20 using this criteria would be 10 and 2. 10 As the length as it is 8 more than the 2 as the width.
The two angles 2y and 4y-36 add up to 180 degrees since they form a straight angle (aka straight line). We'll use this to find y.
(2y) + (4y-36) = 180
2y + 4y-36 = 180
6y-36 = 180
6y-36+36 = 180+36
6y = 216
6y/6 = 216/6
y = 36
If y = 36, then 2y = 2*y = 2*36 = 72
The bottom right corner of the smaller triangle on the left has an angle of 72 degrees
Focus on this same triangle. It has angles 51 degrees (bottom left corner), 72 degrees (bottom right corner) and x degrees (top)
They add to 180 degrees
x+51+72 = 180
x+123 = 180
x+123-123 = 180-123
x = 57
-----------------------------------
In summary,
x = 57
y = 36
