Answer:
Step-by-step explanation:
200 = 2 * 2 * 2 * 5 * 5
To make it a perfect square, you need to multiply by 2
200 * 2 = 400 = 20²
2
Thus, we must multiply 200 by 2, so that the product becomes a perfect square. 400 is asquare of 20. So, the least number is 2, by which 200 must be multiplied so that the product becomes a perfect square.
y = 0.35x + 2.5
7x+12
You do 10x-3x since they both have the x variable they can be combined to make 7x and the 12 is left alone.
I believe you answer would be D
