Answer:

Option A is correct.

Step-by-step explanation:

The polynomial with factors with zeros at 0,-3 and 4 means

x=0 and x =-3 and x=4

this can be written as:

x=0, x+3 =0 and x-4=0

x(x+3)(x-4) =0

f(x) = x(x+3)(x-4)

So, Option A is correct.

Hey I was just wondering if anyone can give me a better explanation on how to work with Negative numbers and and fractions when

Soloha48 [4]

Answer:

see explanation

Step-by-step explanation:

Given

$\frac{6(2a-4c)-6(6a-4b)+3(4b-8c)}{4}$

Distribute the 3 parenthesis on the numerator

= $\frac{12a-24c-36a+24b+12b-24c}{4}$

Collect like terms on the numerator

= $\frac{-24a+36b-48c}{4}$

Divide each of the terms on the numerator by 4

= $\frac{-24a}{4}$ + $\frac{36b}{4}$ + $\frac{-48c}{4}$

= - 6a + 9b - 12c ← factor out - 3 from each term

= - 3(2a - 3b + 4c)

Compare with

X(2a + Bb + Cc) to obtain

X = - 3, B = - 3, C = 4

kolezko [41]

Answer:

given statement is false

Step-by-step explanation:

given data

first time = 100 minutes

fourth time = 81 minutes

solution

as here time for 1st unit is multiply by learning percentage for obtain time for 2nd unit

so here time for 2nd unit divide by time of 1st unit so 100 is here learning curve

so $\frac{81}{100}$ × 100 = 81 percent

but it say 90 percent learning curve

so given statement is false
