Apply cross multiplication

Theo’s sister to paint the fence in 12 hours.
The first option is correct. For the following question, the simplified expression for the volume is 8x3 + 14x2 + 3x.
Hey there!
If x = -3 then replace "x" with -3
New equation: -3^-2
(-1 × 3)^-2
(-1 / 3 )× 3
3 × 3 = 3^3 = 9 (Solving for your denominator)
(-1/3)^2
= (1/9)
This your answer is: 1/9
Good luck on your assignment and enjoy your day!
