Polygons - here we just have triangles - are similar if the corresponding angles are congruent and the corresponding sides are in proportion. Polygons are congruent if in addition to corresponding angles be congruent, corresponding sides are congruent
Answer:
3 x (3 x - 5) (3 x + 5)
Step-by-step explanation:
Factor the following:
27 x^3 - 75 x
Factor 3 x out of 27 x^3 - 75 x:
3 x (9 x^2 - 25)
9 x^2 - 25 = (3 x)^2 - 5^2:
3 x (3 x)^2 - 5^2
Factor the difference of two squares. (3 x)^2 - 5^2 = (3 x - 5) (3 x + 5):
Answer: 3 x (3 x - 5) (3 x + 5)
X=5
Work:
y=2x-10
4x=2x-10
2x=10, then divide 2x on each side
x=5
If you are looking for the average speed, it is 2m/1 sec.
