Answer:
d
Step-by-step explanation:
a + 2b
Given the expression
2(a+2b) - a-2b
Open the bracket
2a+(2)2b- a-2b
2a+4b - a-2b
Collect the like terms
2a-a+4b-2b
Hence the equivalent expression is a + 2b
Answer: angle y is 50°
t + 2t - 30 = 90
3t -30 = 90
3t = 90+30
t = 120/3 = 40 = angle X
Angle y = 2t-30
y = 2*40-30
=80-30 = 50
