Let's solve ~

$\sf {x}^{2} - 10xy + 21 {y}^{2}$

$\sf {x}^{2} - 7xy - 3xy + 21 {y}^{2}$

$\sf x(x - 7y) - 3y(x - 7y)$

$\sf( x - 7y)(x - 3y)$

Hence, the correct choice is ~ A

The diagram shows a sketch of John's yard. He wants to plant grass, so he must calculate the area of the yard. The distance from

Arturiano [62]

The area of the yard is 50,600 square feet.

Option: C.

<u>Step-by-step explanation:</u>

The given information forms a trapezoid.

The AB is the upper base (a) and its length is 200 feet.

The CD is the lower base (b) and its length is 260 feet.

A straight line distance from AB and CD is the height (h) and its measures as 220 feet.

The area of trapezoid A= $\frac{a+b}{2} (h)$ .

A= $\frac{200+260}{2} (220)$ .

= $\frac{460}{2}(220)$ .

=230(220).

=50600 $ft^2.$

Thus the area of John's yard is 50,600 square feet.
