Answer:
we have:
8x³ + 8x² + 6x + 2
= 8x³ + 4x² + 4x² + 2x + 4x + 2
= 2x²(4x + 2) + x(4x + 2) + (4x +2)
= (2x² + x + 1)(4x + 2)
=> if we divide 8x³ + 8x² + 6x + 2 by 4x + 2 => the result is 2x² + x + 1
Step-by-step explanation:
Answer:
Segment BF = 15
Step-by-step explanation:
Segment DE is parallel to segment BC
Segment EF is parallel to segment AB.
Because segment EF is parallel to segment AB, triangles ADE and EFC are proportional. We must find the scale factor which these two triangles are proportional.
24 ÷ 20 = 1.2
Scale Factor = 1.2
18 ÷ 1.2 = 15
Segment EF is parallel to segment AB so segment EF is congruent to segment DB.
hope this helps! ps. im very sorry about the previous wrong question, but i hope this is right (,,>﹏<,,) xx
Answer:
24.4 feet
Explanation:
Let x be the length of the wooden board as shown in the diagram.
Using trigonometry ratio, we can write
cross multiplying we get:
Diving through by 0.819, we obtain
To the nearest tenth, x=24.4 feet.

Answer:
To construct the Square using a compass and straight edge, you have written the steps not in proper order. I am rearranging the steps for you
1. Construct horizontal H J¯¯¯¯¯
2. Construct a circle with point H as the center and a circle with point J as a center with each circle having radius HJ .
3.Label the point of intersection of the two circles above HJ¯¯¯¯¯ , point K, and the point of intersection of the two circles below HJ¯¯¯¯¯ , point L.
4.Construct KL¯¯¯¯¯ , the perpendicular bisector of HJ¯¯¯¯¯ , intersecting HJ¯¯¯¯¯ at point M.
5.Construct a circle with point M as the center with radius MJ .
6.Label the point of intersection of circle M and KL¯¯¯¯¯ closest to point K, point N, and the point of intersection of circle M and KL¯¯¯¯¯ closest to point L, point O.
7.Construct HN¯¯¯¯¯¯ , NJ¯¯¯¯¯ , JO¯¯¯¯¯ , and OH¯¯¯¯¯¯ to complete square HNJO .
