Answer:

Step-by-step explanation:

(f - g)(x)

= f(x) - g(x)

= 3x² + 4x - 8 - (2x - 5) ← distribute parenthesis by - 1

= 3x² + 4x - 8 - 2x + 5 ← collect like terms

= 3x² + 2x - 3 → A

There was a 340,000 cattle placed on feed. Write an equivalent ration that could be used to find how many of these cattle were b

ioda

An equivalent ratio would be 4/10, and the number of cattle would be 136,000.Explanation:The question asks for an equivalent ratio. This means a fraction that is equivalent to the fraction between 700-799, which is 2/5.To create an equivalent fraction, we multiply the numerator and denominator by the same number. Multiplying both by 2, we get (2*2)/(5*2) = 4/10.Tenths are useful when dealing with thousands, because taking a tenth involves getting rid of a zero. This means that 1/10 would be 34000; 4/10 would be 4 times that: 4(34000) = 136000.
