Answer:
x=141
Step-by-step explanation:
(n-2)•180 = Sum of all the interior angles
n = # of sides
(7-2)•180
5•180
900= Sum of all the interior angles
Add all the angles and equal them to 900
125+122+131+x+7+x+107+x-15=900
Add all the numbers up first on the left side
477+3x=900
3x=423
x=141
Answer:

Step-by-step explanation:
Answer:
h = 10 + 8y
Step-by-step explanation:
Given that :
Height of ght if all alien at birth = 10cm
Growth rate per year = 8 cm
Let:
y = number of years since birth
h = alien's height in centimeter
Relationship between h and y
h = Initial height + (growth rate per year*number of years)
h = 10 + 8y
The unit rate of 32 is 12
