Answer:
the answer is
-x-8y=8
or, x + 8y= -8
Step-by-step explanation:
4x - 6y = 13 - (5x + 2y = 5)
or, 4x - 6y = 13
- 5x - 2y = -5
-------------------------
- x - 8y = 8

Step-by-step explanation:
The products of chord lengths are the same for the intersecting chords:
AQ×BQ = CQ×DQ
6×12 = CQ×(38 -CQ)
This gives a quadratic in CQ:
CQ² -38CQ +72 = 0 . . . . . write in standard form
(CQ -2)(CQ -36) = 0 . . . . . factor the quadratic
CQ = 2 or 36 . . . . . . . values of CQ that make the factors zero
The minimum length of CQ is 2 units. (DQ will be 36.)
125/186 cannot be simplified. It is already in simplest form.
Robert is wrong. The surface area of rectangular prism A is 214 square centimeters
The surface area of rectangular prism B is 856 square centimeters
Prism B’s surface area is 4 times greater then prism A’s surface area
Answer:
C. 3x
Step-by-step explanation:
The first two choices give 1 solution each.
The last choice gives an infinite number of solutions.
Choice C. gives no solution.
3x + 9 = 3x
Subtract 3x from both sides.
9 = 0
Since 9 = 0 is false, equation 3x + 9 = 3x has no solution.
