X^2 - 7x + 12 = 0
x^2 - 4x - 3x + 12 = 0
x (x - 4) -3 ( x - 4) = 0
(x - 4) (x - 3) = 0
x = 3 , 4
Check the answer by plugging in 3 and 4 for x, if the equation equals zero then you have your answer.

The distance from point H to point J is 3 units.The value of n is 3.
Step-by-step explanation:
From the graph, point H is at (n,-6)
Point G location will be at (0,-6)
Point J is at (n,-3)
Observing point H(n,-6) and point J (n,-3) you notice that point J is above point H.find how much far is point H from point J.
d= √(x₂-x₁)²+(y₂-y₁)²
d=√(-3--6)²
d=√3² =√9 = 3
Distance H to J is 3 units
Point G (0,-6) and point H (n,-6) have a distance of 3 units same as point H to J
To get the horizontal length will ;
d=√ (n-0)²
d=√n² but d=3 units
3=√n²
9=n²
√9=n
3=n

Answer:
A) 4x^2+20x+25=(2x)^2+2*(2x)*5+5^2=(2x+5)^2
Area=(side)^2, side=sqrt(area)=sqrt((2x+5)^2)=2x+5
B) 4x^2-9y^2=(2x-3y)(2x+3y), these are the dimensions of the rectangle
