What is the area of an equilateral triangle that has 2 yards and a height of 4.25 ft?
RUDIKE [14]
The first thing you need to do is convert the yards into feet. In one yard there are three feet. So 2*3=6 now you can do the triangle area equation. 6*4.25=25.5 then divide by two. 25.5/2=12.75So the area of the triangle is 12.75 ft^2Hope this helps

Find the perimeter of the scale artwork
P=2(l+w)
P=2(2.5+1.75)
=2(4.25)= 8.5 in

1 in = 0.5 ft
8.5in = 0.5(8.5)
=4.25ft = 51 in
the actual perimeter is 51 in or 4.25 ft

4x - 3y = 12<br> 4x - 5y = -4<br> Solve using Elimination
mr_godi [17]

Answer:

{ \rm{4x - 3y = 12 -  -  -  \{eqn(a) \}}} \\ { \rm{4x - 5y =  - 4 -  -  -  \{eqn(b) \}}}

• subtract eqn(b) from eqn(a);

{ \underline{ \rm{  - \binom{4x - 3y = 12}{4x - 5y =  - 4} }}} \\ { \rm{0x + 2y = 16}} \\  \\ { \rm{2y = 16}} \\  \\ { \boxed{ \tt{ \:  \: y = 8 \:  \:   }}} \\

• find x :

{ \rm{4x - 3y = 12}} \\ { \rm{4x - 3(8) = 12}} \\ { \rm{4x = 36}} \\  \\ { \boxed{ \tt{ \:  \: x = 9 \:  \: }}}
