(Algebra 1 )pls help The lengths of two sides of a triangle are shown below:

Side 1: 3x^2 − 6x − 10

Side 2: 9x + 5x^2 − 8

The perimeter of the triangle is 6x^3 + 10x^2 − x − 3.

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

Part B: What is the length of the third side of the triangle? Hint: Take Perimeter minus 2 sides combined.

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)

Corresponding angles are a. always b. sometimes c. never congruent
