Find x for both compound shapes. show your working out.

Q1  Perimeter = sum of all the sides

The length of the unmarked sides are  9 -8 = 1 cm and  x - 3 cm

So x + x - 3 + 3 + 1  + 8 + 9 = 28

2x =  28 - 18

2x = 10

x = 5 answer

Q2

unmarked sides = x - 8 and  and 5 - 2 = 3

x + x - 8 + 3 + 2 + 5 + 8 = 30

2x = 30 -  10 = 20

x = 10 answer

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.

if e is the midpoint of bd, then bd is 14.
