Select the 2 True statements. 2.3 + (-2.3) is equal to zero

(-3.17) + (-4.1) is positive.

-2.6 - (-12/4) is positive

5/2 + (-2.5) is negative

72 - (-100) is negative

So sorry but I calculated I only found the the 2.3 + (-2.3) is equal to zero and that's all I found but I couldn't find the 2 true statement.

step-by-step explanation:

most likely the answer is a.

alice wins if a total of 5 is rolled. finn wins if a total of 9 is rolled.

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
