He pays $135 for 3 years. So that’s $45/year. Considering 900 is your 100%, how many percents are represented by $45 in 900?
1)
You can see that 900 = 9x100.
So you can divide 900 by 9 to get 100.
That means you can also divide 45 by 9 (it’s proportional)
You have 45 for 900, you divide by 9 so you get 5 for 100 -> 5%
Or 2)

It’s a cross-multiplication :
(45 x 100)/900 = 5%
So the interest rate is 5%.

Answer:
C is the answer mark brainliest if satisfied :)
Step-by-step explanation:
You divide all the dimensions of the larger triangle by 4 to get the dimensions of the smaller triangle.
The first one is 43/72 which can’t be simplified
The second one is 17/18
Answer:
2x+h
Step-by-step explanation:
f(x+h) means that wherever there's an x in the function f(x) we plug in a x+h
we have
(x+h)²+9
Let's start with the numerator
(x+h)²+9-(x²+9)
Distribute the exponent
x²+2xh+h²+9-x²-9
Which gives us
2xh+h²
Divide the whole thing by h to give us
2x+h
