Step-by-step explanation:

$a^{2} +(10+10)a+100$

$a^{2} +10a+10a+100$

$a(a+10)+10(a+10)$

$(a+10)(a+10)$

A marathon is 46,145 yards (about 26 miles) long. If Terrence has run 23,561 yards, estimate by rounding to thousands the number

barxatty [35]

Given:

The length of the marathon is L= 46,145 yards.

The length covered by terrence is d = 23,561 yrads.

The objective is to find the remaining distance need to cover by terrence.

To calculate the remaining distance, we will use the relation,

$x=L-d$

On plugging the values in the above relation, we get,

$\begin{gathered} x=46145-23561 \\ =22584\text{ yards} \\ \approx23000\text{ yards} \end{gathered}$

Hence, Terrence needs to run about 23000 yards.
