Find the area of the following shape. Show all work
Pavel [41]

Best way to solve this is by using

\sqrt{s(s - a)(s - b)(s - c)}

where \: s =  \frac{a + b + c}{2}

s=(12+8+17)/2

=18.5

using the formulae

area =43.5

Write an equation of the line that is parallel to 2x + 4y = 6 and passes through the point (6, 4).
notsponge [240]

Answer:

Step-by-step explanation:

Here's a completely valid trick for finding the equation of this new line:

Start with the given  2x + 4y = 6.  Replace that '6' with 'C.'  We need to find C.  To do this, replace x with 6 and y with 4 and calculate C:

2(6) + 4(4) = C, or 12 + 16 = C.  Thus, C = 28, and the desired equation is

2x + 4y = 28, or (in simplified form)    x + 2y = 14
