Answer: D. 3.2
Step-by-step explanation:
Given : In parallelogram LMNO,
LM = 4.12, MN = 4, LN = 5, and OM = 6.4.
Diagonals and intersect at point R.
We know that diagonals of a parallelogram bisect each other.
Since R is the intersection point of both diagonals.
⇒R is the mid point of OM.
Thus OR=

Therefore, OR=3.2
I’m pretty sure I did my math right, hope this helps.
Answer:
(x-8)(x+7)
Step-by-step explanation:
using quadratic formula we have
x= 
we have:
x^2-x-56=0
a= 1 b=-1 c=-56
so we have:
x=(-(-1)+-sqrt(1^1-4*(1)*(-56)))/(2*1)
x=1+-sqrt(1-4*(-56))/(2)
x=(1+-sqrt(225))/2
x=(1+-15)/2
so we have the roots:
x1=(1+15)/2 =8
x2=(1-15)/2=-7
so the answer is (x-8)(x+7)
It’s s=-2 and s=2 because the absolute value makes both of the numbers be positive so either way it’s going to be 2+4=6
