Sarah converts the number 1,500,600 into scientific notation. She writes 1.5006 x 104. Which of the following statements is true? Sarah is not correct because the exponent should be -4.
Sarah is correct.
Sarah is not correct because 1.5006 should be 1.5.
Sarah is not correct because the exponent should be 6.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

lol we need to see what the question is asking about

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
