Answer: Line AC = 36
Step-by-step explanation: The first and most important clue is the fact that points B, D and F are midpoints of the triangle ACE. What this tells us is that point B divides line AC into two equal sides. Likewise points D and F. If point D divides line EC into two equal sides, then line ED equals
39/2 = 19.5
Also, triangle FED is similar to triangle AEC. Since ED is half of EC, and FE is half of AE. Therefore in triangles FED and AEC,
FD/ED = AC/EC
18/19.5 = AC/39
By cross multiplication we now have
(18 x 39)/19.5 = AC
702/19.5 = AC
36 = AC
Therefore line AC = 36
Hold on give me a second i got this
I'm assuming the 2x2y means 2 x squared y
in that case you just pick the biggest factors that both of those share 2xy and 2x^2y both share a common factor of 2xy.
Hey There!
Let's solve this problem together!

Answer:
<h2>Kayla needs 8 boxes of grass seed to cover the whole garden without including the pond.</h2>
Step-by-step explanation:
You can observe a representation of this problem in the image attached.
Notice that the grass seed is gonna be put only in the green zone, out of the pond. So, we need to find each area and subtract them.
The difference is
Now, according to the problem, one box of grass seed covers 15 meters of the garden, let's divide this number with the seed area.
Therefore, Kayla needs 8 boxes of grass seed to cover the whole garden without including the pond.
