Answer:
m=3
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation
Pull out like factors :
-4m + 12 = -4 • (m - 3)
Add 3 to both sides of the equation :
m = 3
Answer:
10
68
Step-by-step explanation:
The median joins the midpoints of AD and CB. It's formula is 1/2 * (5 + 15) = 10 for its length.
If the trapezoid is isosceles, then <A is the same size as <B
5/8=1/2a+2
5a/8=<span>1/2+<span>2<span>a
</span></span></span>5/8a=2a+1/2
5/8a−2a=<span>2a+1/2−<span>2a
</span></span>−11/8a=<span>1/<span>2
</span></span><span><span>(<span>8/−11</span>)</span>*<span>(<span><span>−11/8</span>a</span>)</span></span>=<span><span>(<span>8/−11</span>)</span>*<span>(1/2<span>)

The answer is -4/11
Hope this helps :)</span></span>
