AB¯¯¯¯¯¯ is the midsegment of trapezoid DEFG. What is x? The image is trapezoid DEFG. AB is the midsegment such that A lies on DE and B lies on GF. Length of AB is 12 units, that of DG is 5x - 4 and that of EF is 8x + 2.
A. 2
B. 1
C. −4
D. 12

step-by-step explanation:

try remembering the steps

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
