Answer:
○ C) 256 in.²
Step-by-step explanation:
{a}^{2} + 2a \sqrt{ \frac{ {a}^{2}}{4} + {h}^{2} } = S. A. \\ \\ {8}^{2} + 2(8) \sqrt{ \frac{{8}^{2}}{4} + {12}^{2}} = 64 + 64\sqrt{10}\\ \\ 64\sqrt{10} ≈ 266,3857703 ≈ 256

Step-by-step explanation:
<u>Answer-</u>
<em>Tyler must be </em><em>more than 7 </em><em>years old, so that the ratio of his sister's age to his brother's age is less than 2.</em>
<u>Solution- </u>
Let's assume that,
Age of Tyler = x years, then
Age of his sister = (x+3) years and Age of his brother = (x-2) years
As given that the ratio of his sister's age to his brother's age must be less than 2, so






Therefore, Tyler's age must be more than 7, in order to satisfy the condition.
3x+12=6 will give you x=2
And
-2=4-3x will give you x=-2
Converting decimals into fractions is simple, all you have to do is think about the number, for example .25, if you look at it you realize it's 1/4 of 1, so it's naturally 1/4, you do this with all of them
