Answer:
x² + 2x - 48
Step-by-step explanation:
( x + 8 ) ( x - 6 )
= x ( x - 6 ) + 8 ( x - 6 )
= x*x - 6*x + 8*x + 8*( - 6 )
= x² - 6x + 8x - 48
= x² + 2x - 48
Answer: 160 miles.
Step-by-step explanation:
Equation = $142.40 = .24x + 104
Define Variable = x = number of miles driven
Solve Equation = Subtract 104 from each side:
38.40 = .24x
Divide both sides by .24:
160 = x
The van was driven 160 miles.
Answer:
2
Step-by-step explanation:

Answer:
multiply both sides by 3x + 7
Step-by-step explanation:
this will eliminate the fraction in the equation and therefore make it easier to isolate x
