The diagram shows a pentagon. It has one line of symmetry.
AE= 4x
AB= 2x+3
BC= x+1
All these measurements are given in centimetres. The perimeter of the pentagon is 21cm.
A)Write an equation, in terms of x, for the perimeter of the pentagon.
Your final line should be in the form ax+b= 21 where a and b are.
B) find the value of x

Aperpendicular bisector, cd is drawn through point con ab if the coordinates of point a are (-3, 2) and the coordinates of point b are (7,6), the x-intercept of cd is point lies on cd.

Someone me! if you’re smart you can solve this!

Need to finish my juan wants to build a greenhouse in his back yard. he needs to maximize the ratio of floor area to structure volume in order to provide the most room for plants while minimizing the area to be heated. find the description of the structure that best meets juan’s criteria. a.) a hemisphere with a diameter of 12 feet b.) a cube with a side length of 12 feet c.) a cone with a diameter of 12 feet and a height of 10 feet d.) a square pyramid with a base side length of 12 feet and a height of 9 feet
