2x-8 + 4x+8
2x+4x= 6x
-8+8=0
so your answer is 6x I think.
Answer: but 8x-4
Step-by-step explanation:
I hope this helps you
x=-5 f (-5)=4. (-5)^2 =4.25=100
x=0 f(0)=4.0^2=4.0=0
x=5 f (5)=4.5^2=4.25=100
The area is 84.
What I do it cut the polygon into something easier like a square and rectangle.
Rectangle: 6•12=72
Square: 4•3=12
Add them together and you have 84
Answer:
Step-by-step explanation:
2x + 23 + 9x - 5 = 95
11x + 18 = 95
11x = 77
x = 7
2(7) + 23 = 14 + 23 = 37 = m<ABD
9(7) - 5 = 63 -5 = 58 = m<DBC
