Write the first ten terms of a sequence whose first term is -10 and whose common difference is -2.

-10, -12, -14, -16, -18, -20, -22, -24, -26, -28.

Step-by-step explanation:

first term is -10, now keep adding -2 to each term, so it is:

-10, -12, -14, -16, -18, -20, -22, -24, -26, -28.

This is an arithmetic sequence  with nth term = -10 -2(n - 1).

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

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.
