F(x)=x^2
x=-1→f(-1)=(-1)^2→f(-1)=1
g(x)=1/(2x+3)
g(f(-1))=g(1)→x=1→g(1)=1/[2(1)+3]=1/(2+3)→g(f(-1))=1/5
Answer: Option C.) 1/5
Two lines that intersect to form a right (90º) angle are called perpendicular lines

Answer:
46
Step-by-step explanation
134 + x has to equal 180 because it makes a straight line.
So you do 180 - 134 to get 46
12 to 14=2
14 to 18=4
18 to 26=8
26 to 42=16
The difference between each number doubles each time.
Therefore the next 2 numbers should be 74 and 138.
16x2=32, 42+32=74
32x2=64, 74+64=138
