What is the expression and value of "six less than the quotient of a number and two, increased by ten" when n = 8? 02-6+10; when n = 8, the value is 8.
o 6-9 + 10; when n = 8, the value is 12.
02-6+10; when n = 8, the value is 11.
6- +10; when n = 8, the value is 9.

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.

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
