Given expression is x² - 121
This is called Difference of Squared terms, we have a formula that is given as :-
a² - b² = (a - b) · (a + b)
Now using the above formula in the given expression, we get :-
x² - 121
x² - (11)²
here a = x and b = 11
x² - (11)² = (x - 11) · (x + 11)
but it says that student gave the answer as (x - 11) · (x - 11).
So, student's answer should be (x - 11) · (x + 11) instead of product of two (x - 11) terms.
Answer:
16 square inches.
Step-by-step explanation:
Split the shape into a rectangle and square. To solve for square, just mulitple the 2 sides (2 x 2) and you get an area of 4. To solve for the rectangle, you can multiple the 6 and 2 to get the area of 12. Add the 4 and 12 together and you get 16 square inches. Hope this helps!
