Answer:
No, the triangles are not similar
Step-by-step explanation:
The (reduced) side length ratios, shortest to longest, are ...
12 : 18 : 20 = 6 : 9 : 10
and
5 : 12 : 13
These are not the same, so the triangles are not similar.
Answer:
(2x-3) (2x+3)
zeros, x intercepts: -3/2, 3/2
Step-by-step explanation:
4x^2 -9
We know the difference of squares is a^2 -b^2
This factors into (a-b) (a+b)
Let 4x^2 =a^2
Taking the square root
2x =a
Let b^2 =9
Taking the square root
b= 3
(4x^2-9 ) = (2x-3) (2x+3)
To find the zeros, we set the equation equal to zero
(4x^2-9 ) = (2x-3) (2x+3) =0
Using the zero product property
2x-3 =0 and 2x+3 =0
2x-3+3 = 0+3 2x+3-3 = 0-3
2x=3 2x=-3
Divide by 2
2x/2 = 3/2 2x/2 = -3/2
x = 3/2 x = -3/2
These are the zeros of the equation (which are also the x intercepts)
Answer:
Step-by-step explanation:
Using the distance formula,
So the perimeter is 
11% or 3/9 should be right. Hope it helps :)
We know that
applying the law of sines
a/sin A=b/sin B---------> a*sin B=b*sin A
<span>A = 80°, a = 24, b = 50
sin B=[b*sin A]/a-----> sin B=50*sin 80/24-----> sin B=2.0517
the sines value </span><span>can not be greater than 1
hence
the answer is
zero triangles</span>
