Answer:
+7/2, -7/2
Step-by-step explanation:
Every number has two (2) square roots. 49/4 is a positive ratio of two square numbers, so the square roots are the positive and negative ratio of the roots of those square numbers.
±√(49/4) = ±(√49)/(√4) = ±7/2

<em>Comment on math symbols</em>
The square root symbol (√) is generally interpreted to mean the positive, or principal square root. That is why we put the plus/minus (±) symbol in front of it when we're talking about both square roots.
12 by 15.
12+15+12+15=54 foot perimeter, 12*15=180 square foot area.
There are many ways of solving a system of equation, a very used one is by elimination of variables, which consists in eliminating one of the variables by combining the equations.
Let's do the following combination: (eq 1) + (eq 2)
This means that we add each term vertically:
⇒
When I said "add vertically" means that you add the first term of the first equation with the first term of the second equation. The second term of the first equation with the second term of the second equations, and so on.
This allowed us to remove the "y" temporarily so we can get a linear one-variable equation we can easily solve:
Now that we know the value of "x", we can plug it in any of the starting equations and get "y":
Therefore, our answer looks like this:
Answer:
If I am correct and I understand it its between 40 and 50.
Step-by-step explanation:
Thats because the square is on 40 and ends on 50.
I hope this helped, tell me if something was wrong.
Goodluck!!!!
