Answer:

The value of x is 49 and the value of AB is 90

Step-by-step explanation:

You know that AB and DE are congruent. That information is given to you.

You set the equations equal to each other and then solve.


2x - 8 = x + 38


Subtract x


x - 8 = 38


Add 8.


x = 49


Plug back into 2x - 8 to find the value of AB


2 times 49 - 8


98 - 8


90

Write a formula for this sequence: 8,-1,-10,-19
Romashka [77]
This is an arith. sequence, and the common difference is -9.

a(n+1) = a(n)-9, with a(1)=8.  Thus, if we look at the first term, we see 8; subracting 9 from 8 produces the second term (-1).
