Sheila manages a team of editors at a publishing company. To help determine deadlines, she developed a model based on past projects. In the model below, x represents the number of pages which require editing, and y represents the total number of days required to complete the editing. Which of the following statements is correct? A. Her team can edit 85 pages in one day. B. Her team is comprised of 85 editors. C. Her team can edit of a page in one day. D. Her team completes editing projects in 85 days.

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
