(-5x - 1)(2x + 8)
-10x^2 - 40x - 2x - 8 = 0
-10x^2 - 42x - 8 = 0
10x^2 + 42x + 8 = 0
5x^2 + 21x + 4 = 0
Quadratic Equation yields:
x = -1/5 and x = -4
250 is the answer I think
Answer:
AB = 12
Step-by-step explanation:
Since the triangle is isosceles, the sides AB and BC are congruent. Then you have ...
4x = 2x+6
2x = 6 . . . . . . subtract 2x
4x = 12 . . . . . .multiply by 2
The side AB has length 12.

PERIOD, FREQUENCY OR AMPLITUDE
1. Doesn't change period
2. More of this means more energy
3. Increases as a pendulum swings back and forth faster
4. Measured in cycles per second
5. Measured in meters or centimeters
6. This is decreases with smaller swing
7. If the frequency increases, this decreases
8. Measured in Hertz
9. Measured in seconds
10. if it swings back and forth slower, this decrease
11. As it dampens, this decreases
Answer:
2ft
Step-by-step explanation:
If you have a 3x3 you have a 9ft Sq paper. To have five feet left the removed square must be 4 square feet. 2x2 = 4 therefore 2ft per side
