Answer: Adiya’s method is not correct. To form a perfect square trinomial, the constant must be isolated on one side of the equation. Also, the coefficient of the term with an exponent of 1 on the variable is used to find the constant in the perfect square trinomial. Adiya should first get the 20x term on the same side of the equation as x2. Then she would divide 20 by 2, square it, and add 100 to both sides.

Hello if someone could explain this question that would be great. Thanks.

Answer:

Ok time to get math on

So this would be D

A non-filled in dot means < or > (depending where arrow is pointing)

A filled in dot means ≤ or ≥ (depending where arrow is pointing)

if an arrow points right, then it would be greater than, if arrow points left.. Then its less than

So the graph line is showing that it cannot be equal to AND it is lesser than so the only answer choice that would make the most sense is D

A is greater than which is not the answer

B is only equal to which is way off

C is less than but it is equal which is wrong

D is the only right answer

Hope this helps! :)

10*12= 120 the bottom of the box
10*7.5= 75 one side
75*2= 150 two sides
12*7.5= 90 another side
90*2= 180 two other sides
120+150+180 = 450

Hope this helped :)
