If the area is 120, each length is root(120)
root(120) = 2*root(30)
so the perimeter is:
4 * 2 * root(30) = 8 root(30)
which is approximately 43.8

Answer:
c. x = 7-t; y = -1/(t -7)
Step-by-step explanation:
To find the parametric equation for x, use the equation for t and solve for x.
t = 7-x
x = 7 -t . . . . . . add x-t to both sides
__
To find the parametric equation for y, substitute the equation for x.
y = 1/x
y = 1/(7-t)
To make this match the available choices, we need to multiply numerator and denominator by -1.
y = -1/(t -7)
The parametric equations are ...
x = 7 -t; y = -1/(t -7) . . . . . . matches choice C
Answer:
1080
Step-by-step explanation:
4% of 12000 = 480
600 + 480 = 1080
Can i please get brainlest
12x+6=9x-15 (subtract variables, smaller one)
-9x. -9x
3x+6=-15 (subtract 6 to both sides)
-6. -6
3x=-21 (divide 3)
x=-9
