Answer:

answer is A

Step-by-step explanation:

(3 $x^{2}$ +5x+1) ( $x^{2}$ −2x+4)

=(3 $x^{2}$ +5x+1)( $x^{2}$ +−2x+4)

=(3 $x^{2}$ )( $x^{2}$ )+(3 $x^{2}$ )(−2x)+(3 $x^{2}$ )(4)+(5x)( $x^{2}$ )+(5x)(−2x)+(5x)(4)+(1)( $x^{2}$ )+(1)(−2x)+(1)(4)

=3 $x^{4}$ −6 $x^{3}$ +12 $x^{2}$ +5 $x^{3}$ −10 $x^{2}$ +20x+ $x^{2}$ −2x+4

=3 $x^{4}$ − $x^{3}$ + 3 $x^{2}$ + 18x +4

Aloha!
1 centimeter= 40 kilometers
The distance between the cities in centimeters is 21.7
To get the answer into kilometers, you multiply.
So, 21.7 times 40 which is 868 kilometers.
To answer your question, the distance between Fort Worth and El Paso is 868 kilometers.

Divide 33 into two groups so the ratio is 4 to 7 how do you divide it

Vladimir79 [104]

Split 33 into two numbers that when added up are 33.
So 12 to 21, which when divided by 3, are 4 to 7.
