x - 6(8) = 132
x = 48 + 132
x = 180
180 gallons was in the pool originally.
1.) (x+2) (x+4) (x-4)
2.) (3x-4) (x^2 +3)
3.) 2x(2x-5) (x-4)
4.) (4x+3) (2x^2 +1)
5.) (4x-5) (16x^2 + 20x+25)
6.) (x+2) (x-2) (x^2+3)
7.) 2x^2(2x+3) (4x^2-6x+9)
8.). (4x-1) (x+1) (x-1)
*Hope this helped, good luck :-)
Answer:
x = 4
Step-by-step explanation:
4(2x+9) = 68
8x+36 = 68
8x = 68 - 36
x = 4
Multiply 5 and £14.06 to get £70.30 this is your answer
