Step-by-step explanation:
ax² + bx + c = 0
= ( - b ±
) ÷ 2a
~~~~~~~~~~~
g(x) = 3x - 7
g²(x) = (3x - 7)²
g²(x) = 9x² - 42x + 49
g²( ) = 9(
)² - 42(
) + 49
9( )² - 42(
) + 49 = 8
16k² - 56k + 41 = 0
a = 16 , b = - 56 , c = 41
D = b² - 4ac = ( - 56)² - 4(16)(41) = 512 =
= ( 56 + √
) ÷ 32 =

Answer:
142m
Step-by-step explanation:
This problem can be solved by simply using the pythagorean theorem, as you stated at the beginning of the problem, which is:
You are given the <em>a</em> side and <em>b</em> side that are needed for this equation, so it's all a matter of plugging in the information you have:
Now, because the <em>c</em> is still squared, you must take the square root of 20200 in order to get the length of just side <em>c</em>:
≈142m
