Answer:
b 125
Step-by-step explanation:
first you know that you have 2 and 5 as similar numbers you both square them so that they become a ratio of area which is 4/25 after you do 4/25=20/x and you do cross multiply then you find 125. hope that helped understand.
Answer: 14 / 20 = 70%
Step-by-step explanation:
Since we already have X, I'm guessing all the question asks you to do is plug it in and solve it to get a Y= equation
If I'm right, then the process is
Y=2(3)+1 (putting 3 in place of x)
Y=6+1
Y=7
Which makes 7 your answer
