PLEASE HELP 100 points HURRY The lengths of two sides of a triangle are shown below:

Side 1: 3x - 4x - 1
Side 2: 4x - X+

The perimeter of the triangle is 5x2 - 2x + 3x - 8.

Part A: What is the total length of the two sides, 1 and 2, of the triangle?

Part 3: What is the length of the third side of the triangle?

Part C: Do the answers for Part A and Part B show that the polynomials are closed under addition and subtraction? Justify your answer.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

-3 degrees

step-by-step explanation:

1/4 is the answer if i recall correctly.
