Given that a triangle has two sides of lengths 10 yards and 15 yards, which is a possible length of the third side?

4 yards

15 yards

14 yards

5 yards

I think the answer is 14

Step-by-step explanation:

because the sides which has the 2 smallest numbers should be greater than the 3rd one. so 14 is the only one that adds up with 10 to have a result greater than 15

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
