Line D--E--F E is the midpoint, so DE = EF DE = 15-3x EF = x+ 3 Since DE = EF, 15 - 3x = x + 3 -4x = -12 x = 3 If x = 3, DE = 15 - 3*3, 15 - 9 = 6 EF = x+ 3, so EF = 3 + 3 = 6 That makes
I am a user of this app and yes it help a lot though the hassle of this is needs a load all the time, it helped me in my DC pre-calc and calc class because it had my textbook on there, extreamly useful app, breaks down questions into simpler steps to help understand as well as being very accurate with its answers and the camera very responsive.

Helps me a lot with school work, quizzes, etc, best mathematical app ever. I wouldn't survive without this app/program going through college. However, its still a very helpful app. This app is mind blowing I love it soo much camaa doesn't like to focus some times but its manageable but above all else it has exceeded my expectations thank you guys.

It gives ans quickly and correct. Thanks for the time saver. Literal life saver, i would give this 10 stars if I could, incredibly helpful to explain step by step how to solve the problems and a very useful tool for learning new concepts and remembering old ones.
Find the midpoint of side EF. Figure EFGH is shown. E is at
Do you need all of the coordinates of the midpoint of EF? yes. Use the midpoint formula:((x2+x1)2,(y2+y1)2) Since we need to find the midpoint of EF, we will use the
Midpoint formula
Once you've plugged the appropriate coordinates into the formula, all you have to do is the simple arithmetic that will give you the midpoint of the two line segments. [4] Here's how you do it: [ (5 + 3)/2, (4 + -4)/2] =. [ (8/2)
