Hello there! So the answer would be D: 35 degrees, 60 degrees and 85 degrees. We know this because angles in a triangle sum to 180 degrees. By simply adding each angle up, we can confirm that 35 + 60 + 85 = 180. :)
F(x)=4-2x+x^2
=4-1+1-x-x+x^2
=3+(1-x) - x(1-x)
= 3+(1-x) (1-x)
= 3 + (1 - x)^2
f(x) = (1 - x)^2 + 3
X+3=6
Subtract 3 from both sides
3-3=0
6-3=3
X=3
Answer:
Step-by-step explanation:
2x+4 = 7x-1
4+1 = 7x - 2x
5 = 5x
x = 5/5
x = 1
hope this helps
