Which generic rectangle would be used to factor x^2+7x+6

Rectangle B

Step-by-step explanation:

Given the expression x^2+7x+6, to get the required rectangle we need to factorize first;

= x^2+7x+6

= x^2+6x+x+6

= x(x+6)  + 1 (x+6)

= (x+1)(x+6)

From line 2 we will see that the terms contains x², 6x, x and 6. The rectangle that contains all this terms is rectangle B. Hence option B is correct.

sin3a=12/15

step-by-step explanation:

since one side was multiplied by 3 the other side must also be multiplied by 3.
