Find the product of (3x + 7y)2. 9x2 − 42xy + 49y2 9x2 − 49y2 9x2 + 49y2 9x2 + 42xy + 49y2

Step-by-step explanation:

we know that

In this problem we have

so

substitute

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.

multiple all that
