For this problem, we can set up a proportion using similarity ratios. We know that triangle DEF is similar to triangle PQR, so we know that DE/PQ = EF/QR = FD/RP:
DE/PQ = EF/QR
3/(5x - 25) = 7/(6x + 4)
Cross multiplying, we get:
7(5x - 25) = 3(6x + 4)
35x - 175 = 18x + 12
Now, we can solve for x:
35x - 18x = 12 + 175
17x = 187
x = 11
So, x is 11.
I believe it is 4, but i am not sure.
Answer: 1/3
Step-by-step explanation:
The slope of a perpendicular line is the opposite reciprocal.
For example, if slope of line A is a/b, then slope of line B which is perpendicular will be -b/a.
Substitute 1 and 3 for a and b. Apply the formula and get 1/3.

Answer: 19
Hey there!
When we put a number in scientific notation, we want the first number to be at least 1 and less than 10. There must be a digit from 1-9 in the ones place.
With the number 0.000015, we can move the decimal place 5 places to the right and we have 1.5, which is more than one and less than ten.
Because we moved the decimal place 5 places to the right, 1.5 is multiplied by 10 to the power of -5.
The 5 is the number of places the decimal is moved, and the negative sign is because we moved it to the right.
10^(-5) is the same as 0.00001, just for context.
So, 0.000015 meters in scientific notation is 1.5 x 10^(5) meters.
Hope this helps!
