Answer:
scale factor = 3
Step-by-step explanation:
The scale factor is the ratio of corresponding sides, larger to smaller.
scale factor =
=
= 3
If you would like to calculate the arithmetic mean, geometric mean, and harmonic mean from the following averages, you can calculate this using the following steps:
averages: 56.4, 59.8, 55.8
the number of values: 3
arithmetic mean:
(56.4 + 59.8 + 55.8) / 3 = 57.33
geometric mean:
(56.4 * 59.8 * 55.8)^(1/3) = 57.31
harmonic mean:
3 / (1/56.4 + 1/59.8 + 1/55.8) = 57.28
Answer:

Then just plug in the values depending on the bridge you chose I'm pretty sure
also can I get brainliest?
(2, 12)
Because that is where the graphs intersect.
Just one
11x+25=7x+15
11x - 7x = 15 -25
4x = -10
x = -10/4
x = -5/2
