What is mD?
mD =
(Help please)

Step-by-step explanation:

Given

m < B = 63°

m< D = m <B ( being opposite angles of parallelogram)

m<D = 63°

Hope it will help :)

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.

4+3x is the answer

hope you got it
