Answer:
No,it is a factorized quadratic equation
Step-by-step explanation:
(7+3x)2x expands to 14x+6x² which is a quadratic equation. It can also be written as 6x²+14x+0
It basically (B) since it’s substituting x=0
(5x^7y^2)(-4x^4y^5)=-20x^a y^b
<span>-20 x^11 y^7 = -20 x^a y^b </span>
<span>a = 11, b = 7 thus a: is you answer</span>
Maybe if the photograph was 3x5 you would be able to see it.
![3*20 = 60 5*20 = 100](https://tex.z-dn.net/?f=3%2A20%20%3D%2060%0A5%2A20%20%3D%20100%20)
Knowing that length and width are 20 times bigger
