Answer:
choice f
Step-by-step explanation:
take ∆ abc
ab^2 = ac^2 + ab^2
400 = 225 + ab^2
ab =√ 175
∆aDB
bd = 20-x
ad^2 = 175 -(20-x)^2
∆acd
225 = x^2 + 175 - 400+ 40x - x^2
225 = -225 + 40x
450 = 40x
x = 45/4
<h3>Answer: Choice B)

</h3>
===========================
Explanation:
n = first number
n+2 = second number
Consecutive odd integers are odd numbers that follow one after another. Eg: {3, 5, 7, 9}
Note how I add 2 each time to get the next number. So that explains the "n+2"
Add up n and n+2, then set that sum equal to or larger than 84 like so

We could simplify or solve for n, but I'll stop here since this is what answer choice B is saying.
side note: "at least" means "that value or more". So if I said "at least 10", then I mean "10 or more".
LCM - means least common multiple
Answer:
Your answer is B
Step-by-step explanation:
Take 300 and subtract it by 99 you'll get 201
3 times 67 is 201
Which is why your answer is B!

(P.S, If you could give me the brainlist if i'm right, that will be great thanks!)
Answer:
first Let's find the common difference
an=a1+(n-1)d
let's take A2 that is 18
so 18=7+(2-1)d
18=7+d
d=11
so the next term is going to be 40+11 that is 51
