Answer:
g
Step-by-step explanation:
Area of square = x^2
Area of rectangle = xy
Let x = side of square
Let x + 3 = width of rectangle
Let x + 5 = length of rectangle = y
Here is the set up:
x^2 + (x + 3)(x + 5) = 249
You finish.

Answer:
Between -12 and -13, decimal estimate: -12.2
Step-by-step explanation:
First let's disregard the negative sign, and focus on
. The smallest square below it is
, or 144. The greatest square right above it is
, or 169.
Now we know that
is somewhere between 12 and 13. Likewise
is between -12 and -13. If 12.5 is the square root of 150, it is too high, so we reduce it to 12.2 to 12.3.
Then we can just negate our answer, since we are looking for
, to get about -12.2.
