Answer:
choice 4) 4.5
Step-by-step explanation:
x² = 7.5² + 4² = 56.25 + 16 = 72.25
x = √72.25 = 8.5
8.5 - 4 = 4.5
Answer:
(n + 4) *2 = 11 * 2
Step-by-step explanation:
(n + 4) *2 = 11 * 2
Divide both sides by 2

n + 4 = 11
Just divide one by another and you'll get the ratio
4000/15 = 800/3 ≈ 266,67
So 4000 is 266,67 times greater than 15
