Answer:
x = 17
Step-by-step explanation:
1) Make the bases the same then rewrite.
4 = 2²
2^2(2x - 5) = 2^3x + 7
2) Since the bases are the same, set the exponents equal to each other.
2(2x -5) = 3x + 7
4x - 10 = 3x + 7
4x - 3x = 7 + 10
x = 17
I believe the answer is ten pairs...
The two rows each have 3 pairs touching, and the four columns each have 1, which makes 2*3 + 4*1 = 10
