Having opposite sides parallel is a condition for having a parallelogram. a) necessary and sufficient b) sufficient, but not necessary c) necessary, but not sufficient d) neither necessary nor sufficient

its not b i got it wrong

Step-by-step explanation:

need points to ask question

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
