Step-by-step explanation:

As per midsegment theorem of a trapezoid,

Segment joining the midpoints of the legs of the of the trapezoid is parallel to the bases and measure half of their sum.

Length of midsegment = $\frac{1}{2}(b_1+b_2)$

3). MN = $\frac{1}{2}(18+10)$

= 14

4). MN = $\frac{1}{2}(57+76)$

= 66.5

5). MN = $\frac{1}{2}(AB+DC)$

7 = $\frac{1}{2}(AB+10)$

14 = AB + 10

AB = 14 - 10

AB = 4

6). 15 = $\frac{1}{2}[(3x+2)+(2x-2)]$

30 = 5x

x = 6

A and b are positive integers and a–b = 3. Evaluate the following: 27^ (1/3 b)/9^ (1/2 a)

maxonik [38]

Answer:

1/27

Step-by-step explanation:

27^(b/3)/9^(a/2) = (27^(1/3))^b/(9^(1/2))^a = (3^b)/(3^a) = 3^(b-a)

= 3^(-(a-b)) = 3^-3 = 1/3^3 = 1/27
