Answer:
-x-30
Step-by-step explanation:
<em>first you need to </em><em>distribute</em><em>:</em>
<em>3(x)+3(-6) -4(x)+ (-4)(3)</em>
<em>Then you </em><em>multiply:</em>
<em>3x+(-18)-4x+(-7)</em>
<em>then you </em><em>combine like terms:</em>
<em>3x-4x= -1x </em>
<em>-18+(-7)= -25</em>
<em>simplified:</em>
<u><em>-1x-30</em></u>

Answer:
154 ft
Step-by-step explanation:
A right triangle is formed, where the height of the wheel (h) is one leg, the distance between you and the base of the wheel is the other leg, and the distance between you and the top of the wheel is the hypotenuse (the angle included between the last two sides is 51°)
From definition:
tan(51°) = opposite/adjacent
tan(51°) = h/125
h = tan(51°)*125
h = 154 ft
Heron's formula is named after Hero of Alexendria, a Greek Engineer and Mathematician in 10 - 70 AD. You can use this formula to find the area of a triangle using the 3 side lengths.
Therefore, you do not have to rely on the formula for area that uses base and height. The picture below illustrates the general fro mu la where S represents the semi-perimeter of the triangle ,
