What is a detailed answer to 11(3k+7–2k)–4

Step-by-step explanation:

Firstly, we expand the bracket,

Now, we collect like terms,

As this is not equal to anything, we cannot solve for k.

So simplification is all we can do here.

If the figures/solids are similar, the ratio of the areas is equal to the square of the ratio of the corresponding sides. Let x be the area of the second figure. The equation that would best allow us to answer this item is,
                      (394.2 in² / x in²) = (10.9 / 21.8)²
The value of x from the equation is 1576.8 in².

Thus, the nearest answer is the second choice.
