HELP PLEASE ANSWER!! Tomika plans to run 84 miles in 4 weeks . If she continues the pattern,how many miles miles will she run in
Maurinko [17]

Answer:

She will run a distance of 1095.78 miles per year.

Number of days in a year = 365.25

Number of days in a week = 7

Number of weeks in a year = 365.25/7 = 52.18 weeks.

Tomika plans to run 84 miles in 4 weeks.

Distance run by Tomika in 1 week = 84/4 = 21 miles.

Distance run by Tomika in 1 year = 21*52.18 = 1095.78 miles

So she will run a distance of 1095.78 miles per year.

Hank’s teacher asked him to verify that the product (y−3)(y2 3y 9) is a difference of cubes. He used the distributive property t
kramer

The value of a is 9, the correct option is B.

Given

Hank’s teacher asked him to verify that the product (y−3)(y2+3y+9), is a difference of cubes.

<h3>Quadratic equation;</h3>

The equation which has the highest degree is 2 is called quadratic equation;

\rm ax^2+bx+c=0

Where a, b, and c are the constants.

The given polynomial is;

\rm  (y-3)(y^2+3y+9)

On multiplying the terms;

\rm  (y-3)(y^2+3y+9)\\\\y(y^2+3y+9)-3(y^2+3y+9)\\\\y^3+3y^2+9y-3y^2-9y-27\\\\

On comparing;

\rm ay = 9y\\\\a=9

Hence, the value of a is 9.
