Answer:
lol number 8 is x= i, -i , 
, -4 so u are correct.
and number 7 is x=
or ![\sqrt[5-i]\sqr\frac{23}{8}](https://tex.z-dn.net/?f=%5Csqrt%5B5-i%5D%5Csqr%5Cfrac%7B23%7D%7B8%7D)
Step-by-step explanation:
When 0 is in the numerator, then the whole fraction becomes equal to 0.
However if 0 is in the denominator, then it is undefined.
The height of the isosceles triangle is 8.49 inches.
<h3>
How to find the height of the triangle?</h3>
Here we have a triangle such that two of the sides measure 9 inches, and the base measures 6 inches.
So this is an isosceles triangle.
We can divide the isosceles triangle into two smaller right triangles, such that the side that measures 9 inches is the hypotenuse, the base is 3 inches, and the height of the isosceles triangle is the other cathetus.
By Pythagorean's theorem, we can write:
(9in)^2 = (3 in)^2 + h^2
Where h is the height that we are trying to find.
Solving that for h we get:
h = √( (9 in)^2 - (3in)^2) = 8.49 inches.
We conclude that the height of the isosceles triangle is 8.49 inches.
