It would be an acute triangle because the lengths are below 90 degrees
4a+7b-12c-8a-9b+12d
Now you have to combine like terms, so a and a, B and B etc.
4a-8a=-4a
7b-9b=-2b
No more like term
-4a-2b-12c+12d
Have a nice day
Answer:41 m
Step-by-step explanation:
Lets use the Pythagoras thermos to solve
40^2+9^2=c^2
1600+81=c^2
1681=c^2
41=c
The value of the hypotenuse is 41
I see you already attempted this question and got it right, Good job!
Answer: c/2-4
Step-by-step explanation:
This is what I get :
1/2(c-8)
Distributed property
1/2(c) + 1/2(-8)
Do c and -8 as a fraction with denominator 1 solve across
1/2×c/1+1/2×-8/1
Here you can only divide -8by 2
C/2-8/2
To get -4
C/2-4
