A triangle has side lengths of (3.76 + 1.7) centimeters, (1.36 + 1.1) centimeters, and (7.1c +5.1) centimeters. Which expression represents the perimeter, in
centimeters, of the triangle?

Step-by-step explanation:

our triangle has one length:     3.76+1.7=5.46

                           another side: 1.36+1.1=2.46

                            last side:        7.1+5.1=12.20

Perimeter is=5.46+2.46+12.20=20.12 cm

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
