Answer:
In a triangle, the segment joining the midpoints of any two sides will be parallel to the third side and half its length ⇒DE is parallel to AC, and DE = 8, AC=16.
Similarly, DF is parallel to BC, and DF=6, BC=12
Step-by-step explanation:
Similarly, EF is parallel to AB, and EF=3.5, AB=7
Hence, perimeter of ΔDEF = 8+6+3.5 = 17.5
So the smallest number is 3. As it divides 6,9 and 15.
D
Simplify:
Rewrite in the form :
Add to both sides:
or
x = -4±
x= -4±
Here’s how you find the mean. Find the sum of all the data combined. Then divide the sum by how many numbers of data there are!!
w < 3.3
C) w < 3.3
D) w < 3.3
8316
multiply them all.
