Answer:
rational equation
Step-by-step explanation:
A rational equation is an equation containing at least one fraction whose numerator and denominator are polynomials, \frac{P(x)}{Q(x)}.
Answer:
Top left and bottom right
Step-by-step explanation:
you know there right triangles because the legs squared (two short sides of the triangle) add up to the hypotenuse squared (long side of triangle)
Pythagorean theorem
a²+b²=c²
a=leg, b=leg, c=hypotenuse
Answer:
Area of Rectangle = 
Step-by-step explanation:
Rectangle two vertices lie on x axis ; two vertices lie on parabola 
.
Supposing coordinates of upper right vertex of rectangle are P = 
Due to parabola symmetry, width of rectangle is twice the distance horizontal (X) axis distance between Y axis & point P.
Width of rectangle = 
Length of rectangle = 
;
Area of Rectangle = Length x Width
= 
= 
=
Answer:
whatever y is, x will equal 5.
Step-by-step explanation:
draw a vertical line at 5 on the x axis
The length of the third side is 4 7step-by-step the explanation- the perimeter of a triangle is 16 to the square root of 7 feet.
