Answer:
−4(x−2)+5x
Distribute:
=(−4)(x)+(−4)(−2)+5x
=−4x+8+5x
Combine Like Terms:
=−4x+8+5x
=(−4x+5x)+(8)
=x+8
1. Cross cancel
2. Multiply numerators
4*x²-16 = 4x²-64
3. Multiply denominators
2x+8*1 = 2x+8
4. Divide
5. Simplify
2(x-4)
Answer is 2(x - 4)
since there are 180 degrees in a triangle so :
65+72+y=180 add like terms
137 + y=180 now subtract 137
y= 180-137
y=43 degrees
