Answer:
Step-by-step explanation:
(x-3)² - 7 = (5-3)²-7
= 2²-7
= 4 - 7
= -3

Yes
Yes
No
Step-by-step explanation:
9-12-15 is just a dilation of a 3-4-5, which is right.
6-8-10 is also a dilation of 3-4-5.
However, 2-4-6 is not a triangle. In fact, it's just a line segment, because 2+4=6
Answer:

Step-by-step explanation:
The given equation is:

We have to find the logarithmic equation with same solution as the given equation.
If we take the log of both sides, we can get a logarithmic equation. Since the log operation is applied to both sides the solution of the equation will stay the same.
Taking the logarithm to the base 3 of both sides, we get:

Answer:
6x^2 -29 +35.
Step-by-step explanation:
use the FOIL method(First, Outer,Inner, and Last.)
2x x 3x=6x^2.
2x x -7=-14x.
-5 x 3x =-15x.
-5 x -7=35.
= 6x^2 -14x -15x+35
6x^2 -29x +35.
To do this problem you would need to have at least one side length AND the hypotenuse to figure out the other side length.
