Answer:
11 units^2
Step-by-step explanation:
We know that the area of a square is the side squared, so we can use the inverse of this formula to say the side of a square is the square root of the the area. This gives us√33 and √44 as the side lengths of the red and green squares respectively. Next, we use the pythagorean theorem to find the other side of the white right triangle, which is also a side of the blue square. So:
(√44)^2 - (√33)^2 = side^2
44 - 33 = side
side^2 = 11
side = √11
To find the area of a square, you just square the side, so we get (√11)^2 which is just 11 units^2.
The expression is rewritten in standard form and they are not the same due to the negative.
<h3>What is simplification of an expression?</h3>
Usually, simplification involves proceeding with the pending operations in the expression.
Simplification usually involves making the expression simple and easy to use later.
Both (x−3)(x+3) and (3−x)(3+x) contain a sum and a difference and have only 3 and x in each factor.
Let see the equation formed by the factor;
(x−3)(x+3)
= x^2 + 3x - 3x - 9
= x^2 - 9
(3−x)(3+x)
= 9 + 3x - 3x - x^2
= 9 - x^2
The expression is rewritten in standard form and they are not the same due to the negative.
