The area of the original plot is 200 x 300 = 60000
<span>So the problem says </span>
<span>(x + 200)(x + 300) = 120000 </span>
<span>Proof: 300 x 400 = 120000 </span>
<span>x^2 + 500x + 60000 = 120000 </span>
<span>x^2 + 500x - 60000 = 0 </span>
<span>(x + 600)(x - 100) = 0, so </span>
<span>x = - 600 (reject), x = 100 </span>
<span>So x = 100 meters </span>
<span>Proof: 300 x 400 = 120000</span>
Answer:
2/3
Step-by-step explanation:
Pretty simple to find. Divide both the top and the bottom by 4, and see that it makes 2/3. Easy way to figure out any of these is just to simpliy them. Like 10/12 would equal 5/6
Answer:
10 + 5
Step-by-step explanation:
If you are subtracting a negative then it become adding a positive. A way to remember this is because it has matching socks.
Answer:
x=0.2 to the nearest tenth
Step-by-step explanation:
The given equation is
We apply the distributive property to get:
We group similar terms to get:
x=0.2 to the nearest tenth
