Line 1 to 2: Commutative Property of Multiplication, because all that changed was the order of the things being multiplied.
Line 2 to 3: Commutative Property of *Addition*, because all that changed was the order of the things being added.
All that changed in either step was the ordering of the things being multiplied or added. That’s the commutative property.
Answer:
A and B are the remaining angles because of course a triangle always adds up to 180 degrees so you subtract 125.5 from 180 and get 54.25, then you look for the teo angles that when added together total 54.25 and you have your angle then using your three angles you calculate your area to be 772.04
Step-by-step explanation:
Answer:
A or (2x+1)/(x-1)
Step-by-step explanation:
Let's simplify the top of the fraction first.
1. Simplify the numerator.
2x^2 -7x-4=(2x+1)(x-4)
2. Simplify the denominator.
x^2-5x+4=(x-4)(x-1)
Now we have:
((2x+1)(x-4))/((x-4)(x-1))
We see that there is an (x-4) both on the numerator and denominator.
We can remove (x-4) by division.
Doing that, we have:
(2x+1)/(x-1) or A
The distance between any two points can be found using the Pythagorean Theroem...
d^2=(x2-x1)^2+(y2-y1)^2 in this case
d^2=(2-2)^2+(1--6)^2
d^2=0+49
Since d>0
d=7 units
