3/20T of mulch. Each Flower bed will contain 3/20 tons of mulch
Answer:
We use addition because -16 is negative, and we need to cancel out its value so we add 16 to both sides, leaving 0+x, or x, on the left and combining like terms on the right.

Answer:
we get ![x^2=12-6\sqrt{3}](https://tex.z-dn.net/?f=x%5E2%3D12-6%5Csqrt%7B3%7D)
Step-by-step explanation:
We are given: ![x=3-\sqrt{3}](https://tex.z-dn.net/?f=x%3D3-%5Csqrt%7B3%7D)
We need to find ![x^2](https://tex.z-dn.net/?f=x%5E2)
Note: Since question is not clear, I am assuming that we need to find ![x^2](https://tex.z-dn.net/?f=x%5E2)
Solving:
![x=3-\sqrt{3} \\Taking \ square \ on \ both \ sides\\x^2=(3-\sqrt{3})^2\\](https://tex.z-dn.net/?f=x%3D3-%5Csqrt%7B3%7D%20%5C%5CTaking%20%5C%20square%20%5C%20on%20%5C%20both%20%5C%20sides%5C%5Cx%5E2%3D%283-%5Csqrt%7B3%7D%29%5E2%5C%5C)
We know that ![(a-b)^2= a^2-2ab+b^2](https://tex.z-dn.net/?f=%28a-b%29%5E2%3D%20a%5E2-2ab%2Bb%5E2)
Using formula and simplifying
![x^2=(3)^2-2(3)(\sqrt{3})+(\sqrt{3})^2\\x^2=9-6\sqrt{3} +3\\x^2=12-6\sqrt{3} \\](https://tex.z-dn.net/?f=x%5E2%3D%283%29%5E2-2%283%29%28%5Csqrt%7B3%7D%29%2B%28%5Csqrt%7B3%7D%29%5E2%5C%5Cx%5E2%3D9-6%5Csqrt%7B3%7D%20%2B3%5C%5Cx%5E2%3D12-6%5Csqrt%7B3%7D%20%5C%5C)
So, we get ![x^2=12-6\sqrt{3}](https://tex.z-dn.net/?f=x%5E2%3D12-6%5Csqrt%7B3%7D)
Answer:
Just took the test and got the correct answer :)))
Step-by-step explanation:
Look at the image down below!!
Answer:
if she build x numbers of large decks, therefore small decks would be (x + 5)
1500*(x+5)+2500x =23500
1500x+7500+2500x=23500
4000x+7500 =23500
4000x=23500-7500
4000x=16000
x=4
4+5=9
cho built 4 large decks and 9 small decks
