Hi!
So we need to know how much smaller ΔDEF is than ΔABC.
See line DF compared to AC. PQ is 1.5 times smaller than DF. That means ΔDEF is 1.5 times smaller than ΔABC.
So to find the length of DE, divide AB by 1.5.
27/1.5 = 18
x=18
The length of DE is 18
Hope this helps! :)

Answer:
, explanation for how to get there
Step-by-step explanation:
If we have the equation , we want to isolate c on one side and find it's value.
Let's first divide both sides by 4.
Now let's solve for the absolute value. We know that:
or
Possibility 1:
Subtract 3c from both sides:
Possibility 2:
Add 4c to both sides:
Subtract 5 from both sides:
Divide both sides by 7:
Plugging both of these values into the equation, we can see that only 5 works.
Hope this helped!
-7/2 and -1/2 (there both fractions)
Answer:
(f - g) (x)
Step-by-step explanation:
Since (x) is common between them, you can bring it out. for example,
f(x) = x +1
g(x) = 2x + 3
f(x) - g(x) = x + 1 - 2x + 3
= -x + 4
(f - g) (x) = x + 1 - 2x + 3
= -x + 4
Answer:
229.7
Step-by-step explanation:
The point of a square root is that when you square it, you get the original number.
(√229.7)^2 = 229.7
