The answer HL...................
The area of a triangle is found using the formula Area = 1/2 x base x height.
Base = 8
Height = 18.
The area of 1 triangle = 1/2 x 8 x 18 = 72 square units.
There are a total of 4 sides, so total area = 72 x 4 = 288 units ^2
Answer:
After finding the solution of given equations by elimination method
-3x-3y=12
-9x+3y=-24
we get the value of x=1 and y= -5
Step-by-step explanation:
is eq A
is eq B
To find out value of x and y we will use elimination method
To find value of x add eq A and eq B

Now to find value of y put x=1 in eq A

so the value of
x= 1
and
y= -5
For checking the solution
putting value of x and y in eq A

Hence proved
Putiing value of x and y in eq B

Hence proved

Answer:
$337.5
Step-by-step explanation:
4:5=360:x 360/4=90 90+360=450 check 360/450=0.8 and 4/5=0.8
4:5=360:450
larger farm perimeter is 450 yards so dig a trench 0.75 per yard
so 450 * 0.75 = $337.5
Hope this helps! :)
