-x^ -3x, - 8

While working on the multiplication problem 38 x 25, Maria says this:              “Four times 25 is 100, so 40 times 25 is 1000. Now take away 2, so the answer is 998.” Is Maria’s method correct or not? If it is correct, write equations that incorporate Maria’s work and that show why it’s correct. If Maria’s reasoning is not correct, explain why.  Work with portions that are right to correct Maria’s work, and write a string of equations that corresponds to your corrected method for calculating 38 x 25. In either case, write your equations in the following form:

Hello, Can you explain problem c) I do not understand the solution.

Please help answer this question, thank you so much!

Please show a step-by-step solution. Do not skip steps, and explain your steps. Write it on paper, preferably. Make sure the work is clear.

I am lost on what to do. I've tried to list what I know, but I got confused and have no leads. I'm working on Problem 3. Pleases help and show steps how to work out problem.

A tortoise and hare are competing in a 400-meter race. The arrogant hare gives the tortoise a 220-meter head start. When the start gun is fired, the hare begins running at a constant speed of 3.5 meters per second and the tortoise begins crawling at constant speed of 1.5 meters per second. Take out a piece of paper and read the above problem context again. You will prepare your written work and solutions on your own paper and upload it and the end of this question. Complete the problem solving process by: i. reading and re-reading the problem to identify the quantities in the situation; ii. making a drawing to represent the relevant quantities in the situation; iii. and defining the variable t to represent the number of seconds since the start of the race. a. Define a function f to determine the distance of the tortoise from the finish line in terms of the number of seconds, t, since the start of the race. Preview Solve f(t) = 0 and describe what your solution represents. t = Preview…

I am only needing help on the second picture I can not figure out how to simply this.
