The temperature on a summer afternoon is 76°f. define a variable and write an expression to find the temperature after it changes. then evaluate your expression for a decrease of 8 degrees fahrenheit.

76 – c; 76 – (–8) = 84; 84°f

8 + c; 8 + (–76) = 84; 84°f

8 – c; 8 – (–76) = 68; 68°f

76 + c; 76 + (–8) = 68; 68°f

hope this !

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

c-   36

taxicab circle radius 9 has 4(9) = 36 points

c.

step-by-step explanation: it's not a. because 1/3 x 1/3 x 1/3 = 1/27 so that's not correct. | b. is also not correct because 7 x 7 1/3 is not actually 3 x 7 1/3 . and for d. multiplications are not additions so that left you with c. ( hope this out : d )
