Let Q be the point (a, b). Since the midpoint of P (2, 3) and Q (a, b) is (4, 6), we have
(2 + a)/2 = 4
(3 + b)/2 = 6
Solve for a and b :
(2 + a)/2 = 4
2 + a = 8
a = 6
(3 + b)/2 = 6
3 + b = 12
b = 9
So the coordinates of Q are (6, 9).
Use synthetic division. Look at my attachment below for a detailed explanation. If the remainder is 0 (which it is), then it's a factor.
Answer:
85
Step-by-step explanation:
If you add all the sides then add 2 (from the 4x-2) then you'll get 8x.
340/8=85
x=85
