Answer:
x = 5 (see below)
Step-by-step explanation:
Combine like terms by subtracting on both sides:
25 + 8x = 5 + 12x
20 = 4x
Then divide:
20 = 4x
5 = x
Move the variable to the left side of the equation:
x = 5
Step-by-step explanation:
Ans 6 Use Pythagoras theorem...
Hypotneuse²=Base²+Height²
6²=4²+H²
36-16=H²
20=H²
√20=H
√2×2×5=H
2√5 = H....
hope it helps
