Answer:
-14
Step-by-step explanation:
plug 3 into x
multiply -6 by 3=-18
-18 +4 =-14
I can see that 2 is a root but not 1? So I tried -1 by substitution and that works.
So to work out the 3rd root we just use the sum and product of roots theorem.
We have the sum of the roots = 11/7 and from there the third root is 4/7
Answer:
True
Step-by-step explanation:
The answer is a. 16x+h
Since a triangle is isosceles, its both legs are the same. So, we have two sides and a hypotenuse (a, a, and h)
A midsegment length (m) of a triangle is a half of a parallel bottom leg of the triangle (a):
a = 2m
The perimeter (P) of the triangle is the sum of its sides:
P = a + a + h
It is given:
m = 4x
Since a = 2m, we have:
a = 2*4x = 8x
Therefore, the perimeter is:
P = a + a + h = 8x + 8x + h = 16x + h
