Answer:
4(3x-y)
Step-by-step explanation:
Given:
To factor this kind of expression, first, find the common factor.
Notice that in the expression, we have both same (3x-y). Therefore, (3x-y) is our factor.
Let u = 3x-y
Change u back to 3x-y:
Therefore, the factored expression is 4(3x-y).
The Pythagorean theorem is a^2+ b^2= c^2.
The variables, A and B are the legs of the triangle and c is the hypotenuse of the triangle.
We can use the Pythagorean theorem to find any side of the triangle when two of the sides of the triangle is known.
Hope this helps!
Answer: not a right triangle
Step-by-step explanation:
if it is a right triangle the pyth. theorem must stand
12^2+12^2 does not equal 15^2
so it is not a right triangle
Answer: C. 10
Explanation:
Take half right triangle from the isosceles triangle:
We get side lengths:
12/2 = 6, 8, and x
And use Pythagorean’s theorem to find x:
6^2 + 8^2 = x^2
36 + 64 = x^2
100 = x^2
10 = x
