-16t^2+400=0
16t^2=400
take square root on both sides.

4t=20
t=20/4
t=5
Answer:
165
Step-by-step explanation:
First, m<UTS=m<UTV+m<VTS by Angle Addition Postulate. Then, you substitute all the values that you provided for the angles. 15x+15=x+15+140. You then solve for x.
15x+15=x+155
14x=140
x=10
You then plug back in 10 for X in the value of m<UTS. 15(10)+15=165
Answer:

Step-by-step explanation:
Let points D, E and F have coordinates
and 
1. Midpoint M of segment DF has coordinates

2. Midpoint N of segment EF has coordinates

3. By the triangle midline theorem, midline MN is parallel to the side DE of the triangle DEF, then points M and N are endpoints of the midsegment for DEF that is parallel to DE.
ANSWER
a.)17
EXPLANATION
The given function is

We want to find the remainnder when this function is divided by x-3 using synthetic division.
We write the coefficients of the given function and carry out the synthetic division as shown in the attachment.
The remainnder is 17.
