Answer:
I'm going to assume that the percentage sign means divide.
52
Step-by-step explanation:
8*6+(12-4)/2
8*6+(8)/2
48+8/2
48+4
52
If you divide 90 to 18, you would get 5. therefore, 5cm is the answer.
The distance between two points is given by:
d² = (x₂-x₁)² + (y₂ - y₁)²
9 = (x₂ - 4)² + (y₂ - 2)²
Now, we can check different ordered pairs in this equation to see which satisfies it:
The one that satisfies this equation is (4 , -1).
1/10*(f-220) or 0.1(f-220)
