Answer:
Step-by-step explanation:
Animals that have three stages in their life cycles go through
3X - 4Y = 9
-3X + 2Y = 9
first step is try to get rid of one of the variables and solve for the other one. In this example you dont need to manipulate the equations to get one variable to cancel.
the x term cancels out. add both equations
-2y = 18
y= - 9
now we plug the y term back into an original equation and solve for x
3x - 4(-9)=9
3x=-27
x=-9
hope that helps
side, s = 1/3ft
area, a = 6s^2
a = 6 × (1/3)^2 = 6/9 = 2/3 sq ft

Answer:
Step-by-step explanation:
The Pythagorean theorem applies to right angled triangles only.
However, for any other triangle, by dropping a perpendicular from any vertex on to the opposite side, you form two right angled triangles both of which can be solved by the Pythagorean theorem.
So, the Pythagorean theorem applies to right angled triangles directly and to other triangles indirectly.
