Answer:
The triangles are not similar.
Step-by-step explanation:
Look at ratios of corresponding sides. If the triangles are similar, all the ratios will be equal.
Compare a side from 
with a side from 
.
16/20 = 4/5
12/15 = 4/5 (looks promising, so far!)
20/26 = 10/13 Not at all the same as 4/5, so the triangles are not similar.
Answer:
y = r / (k+v)
Step-by-step explanation:
First, you use the distributive property and take out y: y(k+v)=r
Then you divide both sides by (k+v): y<u>(k+v)/(k+v)</u> = r/(k+v)
Finally you get y = r / (k+v)
Answer:
722.24 cm
Step-by-step explanation:
The volume formula is L X W X H = V so using that information we can do 18.5 times 32 times 12.2 which gives us 722.24 cm.
Answer:
f(x) = 3 + 5x
Step-by-step explanation:
For this problem, we can see a simple pattern whereas x increases by 1, y is increasing by 5.
This means that f(0) = 3.
And to create the function, we simply use f(0) summed with the increasing 5 multiplied by the input x.
Hence, we will create the function equation:
f(x) = 3 + 5x

- h(x) = f(x) + g(x) =
- h(x) = g(x) – f(x) =
- h(x) = 4g(x) =
<u>Step-by-step explanation:</u>
Here we have , f(x) = -2.5x + 12; g(x) = 21x - 28 or 
.
