Answer:
12
Step-by-step explanation:
16^2+b^2=20^2
256+b^2=400
b^2=144
b=sqrt144
b=12

The missing aspect of this question is shown in the attached image, which is that the letters correspond to vertices of a parallelogram.
A key feature of the parallelogram is that the diagonals bisect each other, therefore:
PT = TR
QT = TS
With this information we can now plug in the equations and solve for the variables x and y.
PT = TR
2x = y+4
y = 2x - 4
QT = TS
x + 2 = y
We now have two equations for the variable y. With this we can solve for x.
2x - 4 = x + 2
x = 6
y = x + 2
y = 6 + 2
y = 8
Once we solved for the variable x, we simply placed that value back into one of the previous equations and solved for y. The results are
x = 6, y = 8.
Answer:
The statement is wrong. a-b can be positive but not always.
Step-by-step explanation:
There can be three possible situations that are:
- a>b
- a<b
- a=b
Now taking first condition, the result will be positive because a smaller integer is subtracted from a greater one. Such as 5-2=3
In second condition, the result will be negative because a greater integer is subtracted from smaller one. Such as 2-5= -3
In the third condition, the result will always be zero because both the integers will cancel each other. Such as 5-5=0
