In getting the area of and equilateral triangle, you must first consider that all of its sides are congruent and that is 3 inches, so the formula in getting the area is height form its base so in getting its height you must use the pythagorean theorem by dividing the triangle so the hypotenuse of it is 3 and the base of 1.5inches, so the height is 4.77 inches then the area is 7.15 sqr.inch

How do you find the area of the shaded region
Amiraneli [1.4K]

well, first off, let's notice that we have a trapezoid with a rectangle inside it, so the rectangle is really "using up" area that the trapezoid already has.

now, if we just get the area of the trapezoid, and then the area of the rectangle alone, and then subtract that area of the rectangle, the rectangle will in effect be making a hole inside the trapezoid's area, and what's leftover, is the shaded section, that part the hole is not touching.

\bf \textit{area of a trapezoid}\\\\ A=\cfrac{h(a+b)}{2}~~ \begin{cases} h&=height\\ a,b&=\stackrel{parallel~sides}{bases} \\\cline{1-2} h&=8\\ a&=16\\ b&=8 \end{cases}\implies A=\cfrac{8(16+8)}{2}\implies A=96 \\\\\\ \stackrel{\textit{area of the rectangle}}{(5\cdot 3)\implies 15}~\hfill \stackrel{~\hfill \textit{shaded area}}{\stackrel{\textit{trapezoid}}{96}~~ - ~~\stackrel{\textit{rectangle}}{15}~~ = ~~81}

How many solutions does the system have?<br> y = -3x +9<br> 3y = -9x + 9
Trava [24]

Answer:

{y,x} = {0,1}

Step-by-step explanation:

// Solve equation [1] for the variable  y

 [1]    y = 3x - 3

// Plug this in for variable  y  in equation [2]

  [2]    -3•(3x-3) - 9x = -9

  [2]     - 18x = -18

// Solve equation [2] for the variable  x

  [2]    18x = 18

  [2]    x = 1

// By now we know this much :

   y = 3x-3

   x = 1

// Use the  x  value to solve for  y

   y = 3(1)-3 = 0
