To complete a square for ax²+bx+c, you first make a=1.
in this case, a is already 1
move c to the right side: x²+14x=-47
next, add (1/2 of b)² to both sides, in this case, b=14, half of 14 is 7, so x²+14x+ 7²=-47+7²
the left side is now a perfect square: (x+7)²=2
x+7=√2 or x+7=-√2
x=√2-7, or x=-2-√7
Answer: Add 11 to the other side of the equation, giving you 81. Then, since x is square you are going to need to square root both sides ( this symbol). When you do that, you should get what x is! Let me know if you still need help!
Answer: x = 13.5
3/4 = x/18
⇔ x = 3/4 .18 = 27/2 = 13.5
Step-by-step explanation:
Drivers should not drink and drive. I hope this helps if not hopefully someone helps out
The midsegment theorem says that the midsegment is half the third side and parallel as well. 20*2 is 40 so x = 35
