b) 1/2(16x + 8) = 8x + 4
c) 2(4x + 2) = 8x + 4
d) 2x(4x + 2) = 8x² + 4x
Answer: m = -2
Step-by-step explanation:
8(3m+5)=2m-4
24m + 40 = 2m - 4

m = - 44/ 22
m = -2
Answer:
The land area of country A and country B are 80223 sq.km. and 79750 sq.km. respectively
Step-by-step explanation:
Let the area of Country B be x
We are given that Country A is larger by 473 square kilometers.
Area of Country A = x+473
Total area of both countries = x+x+473
Total area of both countries = 2x+473
We are given that The combined land area of the countries A and B is 159,973 square kilometers.
So, 


x=79750
Area of Country A = x+473=79750+473=80223 sq.km.
Hence the land area of country A and country B are 80223 sq.km. and 79750 sq.km. respectively
