y = 4x+4
y = -3x-3
so 4x+4=-3x-3
7x=-7
x=-1
so (-1,0)
Here's your answer, I hope you understand this. 30.9cm
Answer:
C. 60
Step-by-step explanation:
x + 10 = 70
Subtract 10 from both sides
x + 10 - 10 = 70 -10
Simplifying
x = 60
I think is 12..........
the sum of all angles in a triangle is always (ALWAYS !) 180°.
180 = 31 + 35 + x = 66 + x
x = 180 - 66 = 114°
