8 0

Answer:

Step-by-step explanation:

It is D because A would be 8:13, B would also be 8:13, and C would be 13:21. Also, we know that D is correct because for every 13 passes, Harrison catches 8 which is 13 to 8 or 13:8.

What pattern is represented by the polynomial ?

Ymorist [56]

Answer:

choice C. Perfect square trinomial is correct.

Step-by-step explanation:

We need to find the pattern which is represented by the polynomial $4x^2+12x+9$ .

To find that pattern, we need to factor $4x^2+12x+9$

$4x^2+12x+9$

$=4x^2+6x+6x+9$

$=2x(2x+3)+3(2x+3)$

$=(2x+3)(2x+3)$

$=(2x+3)^2$

which is a perfect square.

Hence choice C. Perfect square trinomial is correct.

kolezko [41]

Wesley will need 10 10-inch stones, and 9 5-inch stones.

Since he wants to begin and end the pattern with 10-inch stones, we put a 10 at the beginning and end.

10 5 10 5 10 5 10 5 10 5 10 5 10 5 10 5 10 5 10

10 x 10-inch = 100 inches
9 x 5-inch = 45 inches

100 + 45 = 145 inches
