What is the area of an equalateral triangle of side length x?
OLEGan [10]
First you need to make a line that is perpendicular to one side. The diagram is shown below. then the length of the line that is perpendicular to the triangle is
\frac{ \sqrt{3}x }{2}
then the area of the equilateral triangle equals to
\frac{1}{2} height  \times base
so the area would be
\frac{ \sqrt{3} {x}^{2}  }{4}

Write and solve an equation to answer the question. 14 is what percent of 70?
slamgirl [31]

Answer:

20%

Step-by-step explanation:

An equation is 14=x/100*70 or 14=(x%)*70, either one works

solve for x:

  1. 14=x/100*70
  2. 14/70=x/100 (Divide each side by 70)
  3. 1/5=x/100 (Simplify 14/70)
  4. 100/5=x (Multiply each side by 100 to isolate x)
  5. x=20 (Simplify 100/5)
  6. 20% (Rewrite as a percent)

hope this helps!!
