x * x = x^2
x * .7 = .7x
-6 * x = -6x
-6 * .7 = -4.2
x^2 + .7x - 6x -4.2
x^2 - 5.3 - 4.2
x = 6
Answer:
B
Step-by-step explanation:
Answer: The length is 20.
If UW is the line segment, then the length of VW and UV has to equal to the length of UW
VW = 6
UV = 14
6 + 14 = 20
6 and 7
10(13-X) + X= 13-9X. 3×2=6. 7-6=1. 7+6=13
