Step-by-step explanation:
5x 3 1/2 = 3 x 5 1/2 is false
Answer:

Step-by-step explanation:
This is what is called the Midsegment Theorem, which states that the relation of a triangle's midpunkt is parallel to the triangle's third side, and the mid-segment length is half the third side length, so you would take half of
and set that expression equal to the midsegment:
2x + 10 = 3x
-2x - 2x
____________

You then plug this back into both expressions above to get the double-segment of 60 and the mid-segment of 30. We can tell this is correct because 30 and 60 are relatively proportional to each other.

48 mm long
Since a square has all equal sides, it will be 12mm for all sides
Perimeter = L (Length) + W (Width) + L + W
(In this case since it’s a 2D shape)
12 + 12 + 12 + 12 = 48
Hope this helped :)
Answer:

Step-by-step explanation:
Remember that the formula for the difference of squares is
. The formula implies that if (5x - 8) is a factor, then (5x + 8) is the other factor. We can use our formula to find which one is our difference of squares:



We can conclude that the correct answer is
.
