14. The diagonals of square ABCD intersect at E. If AE = 2, find the perimeter of ABCD.
lutik1710 [3]

Answer:

B, 8\sqrt{2}

Step-by-step explanation:

Diagonals of a square are congruent so AC= 4

using pythagorean theorem we can then do x^{2} +x^{2}=4^{2}

2x^{2} = 16\\x^{2} =8\\x=\sqrt{8} \\x=2\sqrt{2}

Then for perimeter we times the 2\sqrt{2} by 4 and get

8\sqrt{2}

Hope this helps and please mark brainliest!!

Two artists are mixing up green paint for a mural. The first artist, Shane, mixes 3 parts blue and 2 parts yellow to make a shad
11Alexandr11 [23.1K]

Answer:

Shane's green paint mixture with be more yellowish because the sum of yellow paint is much closer to mixing than the Nora's paint. I don't really

Step-by-step explanation:

because the sum of yellow paint is much closer to mixing than the Nora's paint. I don't really know how to say it. Wait

If you really think about it when 3 parts blue and 2part yellow it means that there 1 more blue than yellow

But if you mix 5 parts blue and and 3 yellow it means that there are 2 more blue than yellow. As we know yellow is a lighter color so its harder to keep the color while mixing and having more blue means that the mixture will be less yellowish more blueish or how we say it. i dont really know how to explain it better but the answer is for sure right
