BRAINLIEST AWARD WILL BE GIVEN! PLEASE HELP WITH MATH IVE BEEN ASKING FOR HOURS! PLEASE ANYONE!!!1)Solve the following equation by identifying all of its roots including all real and complex numbers. In your final answer, include the necessary steps and calculations. Hint: Use your knowledge of factoring polynomials.(x^2 + 1)(x^3 + 2x)(x^2 - 64) = 02) Solve for the roots of x in each of the equations below.x^4 - 81 = 0x^4 + 10x^2 + 25 = 0x^4 - x^2 - 6 = 03)Solve for the roots in the equation below.x^4 + 3x^2 - 4 = 0

The table below shows the surface area y, in square feet, of a shrinking lake in x days:Time (x)(days) 10 20 30 40Surface area (y)(square feet) 100 90 80 70Part A: What is the most likely value of the correlation coefficient of the data in the table? Based on the correlation coefficient, describe the relationship between time and surface area of the lake. [Choose the value of the correlation coefficient from −1, −0.99, −0.5, −0.02.] (4 points)Part B: What is the value of the slope of the graph of surface area versus time between 20 and 30 days, and what does the slope represent? (3 points)Part C: Does the data in the table represent correlation or causation? Explain your answer. (3 points)Use the functions h(x) = 5x − 2 and t(x) = 4x + 6 to complete the function operations listed below.Part A: Find (h + t)(x). Show your work. (3 points)Part B: Find (h ⋅ t)(x). Show your work. (3 points)Part C: Find h[t(x)]. Show your work. (4 points)Part A: Factor 3x2y2 − 2xy2 − 8y2. Show your work. (4 points)Part B: Factor x2 + 10x + 25. Show your work.

Select the correct answer from the multiple choice below. Sully’s car has an average fuel economy of 28 miles per gallon. The capacity of the fuel tank is 16 gallons. If Sully completely fills the tank, which function represents the number of miles the car can go without refueling in terms of the gallons of fuel it consumes? (Hint: Convert the car’s fuel tank capacity in gallons to the number of miles the car can travel.)A. y=265-16xB. y=448-16xC. y=448-28xD. y=16-28xE. y=256+16x
