Start with B=A-573. --> A+B=154,973.--> A+(A-573)=154,973. --> 2A-573=154,973. --> 2A = 154,400. --> A = 154,400/2 = 77,200. A= 77,200. 
To find B. :: 77,200+B=154,973. Subtract A from combined area.--> B = 77,773

Answer:

The vertex or top is ( 2, -9)

Step-by-step explanation:

Given y = (x - 5 ) * ( x + 1 )

x² - 4x - 5

See attachment.

The vertex of the parabola is the Top.

The vertex of a parabola is the point where the parabola crosses its axis of symmetry.

If the coefficient of the x² term is positive, the vertex will be the lowest point on the graph, the point at the bottom of the “ U ”-shape. If the coefficient of the x² term is negative, the vertex will be the highest point on the graph, the point at the top of the “ U ”-shape.

The standard equation of a parabola is it

y = ax² + bx + c.

But the equation for a parabola can also be written in "vertex form": y = a(x−h)² + k

In this equation, the vertex of the parabola is the point (h,k) = (2, -9)

The tile along the edge of a triangular community pool needs to be replaced.
Gre4nikov [31]

Answer:

Third option: 12x^2+8x+25

Step-by-step explanation:

s1=8x^2

s2=4x^2+15

s3=8x+10

Total perimeter of the pool edge: P

P=s1+s2+s3

Replacing s1, s2 and s3 in the formula above:

P=(8x^2)+(4x^2+15)+(8x+10)

P=8x^2+4x^2+15+8x+10

Adding like terms:

P=12x^2+8x+25
