Pythagorean theorem- a^2+b^2=c^2
a= 10
b= 15
c= ?
10^2+15^2=?^2
100+225=?^2
325=?^2
√325=?^2
18.027....
Vector AB can be calculated:
AB = <bx-ax , by-ay>
AB= <-5-4 , 1-3>
AB= <-9 , -2>
AC = -2*AB
AC = -2 *<-9 , -2>
AC = <18 , 4>
Now we can calculate coordinates of point C:
AC = <cx-ax , cy-ay>
<18 , 4> = <cx-4 , cy-3>
18=cx-4
cx=22
4=cy-3
cy=7
Coordinates of the terminal point C (22,7).

corect answers is I. 11n + 33
(3 x 3) + (8 x 2) = ?
Using the order of operations you do what is inside the parentheses first, so multiplying the numbers, and then you add the products together.
