Answer:
x² - 5x - 36
Step-by-step explanation:
Use FOIL (First, Outside, Inside, Last) to solve. x times x is x², so that is the first term of our trinomial. The outside terms are x times 4, or 4x. The inside terms are -9 and x, so -9x. The last terms are -9 times 4, or -36. We can add the like terms of 4x and -9x to get -5x. So, your trinomial is x² - 5x - 36.

the answer to your question is400 miles
You would add like terms so it would be 1x then you add 1 to 7 so you would get 8.. the you divide both sides by 1x and you'd get 8=x
Answer:
200
Step-by-step explanation:
i did a little bit of guessing and checking but the answer is 200 because if you multiply 200 by 1 it comes out to 200 and if you multiply it by .26 it comes out to 52. you multiply by .26 because it was 26% and you need to move the decimal over 2 when changing to decimal form. to find it immediately, you multiply 200 by 1.26 and it comes out to be 252 (sorry about the sloppy handwriting)
