If patio is square it means that area of if is

where a is one side
Now we can substitute A=200 and solve eq

a=

a=14.1421
Now we are rounding to the nearest tenths
a=14.1 because next number is 4 and is less then 5.
The result is 14.1
T=2 the solution set is t=2
This is the answer for the first one
Replace x with and simplify
2x - 10

Answer:
You can’t add 3x with 2x because to get term to the other side of the equal sign, you need to do the inverse (opposite) of the number. Since 3x is positive (basically with a + in the front) you SUBTRACT 3x for it to get to the other side. Which will get u -1x or just -x.
