The legs of a right triangle are the sides that are connected to the 90 degree (right) angle. The remaining side is called the hypotenuse.
Another way to look at it is the two legs of a right triangle are the two shorter sides. The longest side is the hypotenuse.
It's A. All you have to remember here are your rules of translations. If there is side to side movement within a parabola it will be indicated within a set of parenthesis with the x coordinate. If there is no set of parenthesis with the x there is no side to side movement. The quantity

tells us that the vertex has moved left 3 units.
Answer: if u a math person shouldn't u know how to do it?
Step-by-step explanation:
Given, the plot is in the shape of triangle.
First side = x meter
Second side = ( 5x-3 )meters
Third side = ( 7x-6 ) meters
Perimeter of triangle is equal to the sum of all the three sides.
Perimeter = 
Combine like terms by adding all the x terms together and all the constant terms together.
Perimeter = 
Perimeter =
feet ... Answer
9x(y+4)-10(y+4)
(9x-10)(y+4)
