Perimeter of a triangle =sum of all sides
=2x-7+5x-3+2x-2
=2x+5x+2x-7-3-2
=9x-12
Answer:
AB=8
Step-by-step explanation:
First, you get figure out x. Since both sides are equal, use the equation x+3=2x-2, then subtract x from both sides, 3=x-2, and then add 2 to both sides, x=5. Then use one of the equations to get the length of the side, I used x+3=8, which is your answer.
(hope this helps :P)
Step-by-step explanation:
y=x+6.......(1)
y=-3X-6....(2)
from eq (1), we get,
x=y-6....(3)
sub eq (3) in eq (2), we get
y= -3(y-6)-6
y= -3y+18-6
y+3y-12=0
4y=12
y=3
sub value of y in eq (3)
x=3-6
x=-3
Answer:
y= 1/-2x - 2

Answer:
360 ft
Step-by-step explanation:
<h3>Given</h3>
- Area = 57600 ft²
- Length = x
- Width = 4/9x
<h3>Solution</h3>
- A = lw
- x*4/9x = 57600
- 4/9x²= 57600
- x² = 57600*9/4
- x² = 129600
- x = √129600
- x = 360 ft
