Drag each scenario to show whether the final result will be greater than the original value, less than the original value, or the same as the original value. 1- A 70% increase followed by a 50% decrease
2- A $35 decrease followed by a $25 increase
3- A 50% decrease followed by a 100% increase
4- A 30% increase followed by a 15% decrease

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
