Solve the system of equations
4x2 - 8x + 1
3x2 - 7x - 6
Multiply the 2nd line by -1
4x2 - 8x + 1
-3x2 + 7x + 6
Add the lines together
x2 -x + 7
Answer: a)
opposite angles in a quadrilateral inscribed in a circle are supplementary (they add up to 180 degrees)
In this quadrilateral, point O and point Q are opposite to each other, meaning they add up to 180 degrees
So,
O+Q=180
x+17 + 6x-5 =180
7x+12=180
7x=168
x=24
you are trying to find the measure of angle ROP and this is the same as angle O which was given to be x+17
But now you know x is 24 degrees so x+17 = 24+17 = 41 degrees
Answer:
B) 102 units
Step-by-step explanation:
The diagonals of a parallelogram bisect each other. This means ...
BE = ED
3 -9x = -8x +14
-11 = x . . . . . . . . . . . . add 9x -14
BE = 3 -9x = 3 -9(-11) = 3 +99
BE = 102 units
