Answer:

x +3 = x^2 +2x -4

Step-by-step explanation:

Straight substitution of the top expression for y gives you ...

x +3 = x^2 +2x -4

This lets you rewrite the equation to standard form as ...

x^2 +x -7 = 0

and find the solutions to be ...

x = (-1±√29)/2

Corresponding y-values will be 3 more than this:

y = (5±√29)/2

The area if the rectangle is 1,035 square centimeters. If the length of the rectangle is 3 centimeters, what is the width of the

omeli [17]

<span>x = length cm
y = width cm
---
y = 3
xy = area
xy = 1035
x*3 = 1035
x = 1035/3
x = 345

so the answer is 345</span>

The city of Orlando’s building a dog park in downtown Orlando dog park will be triangular shaped as shown on the coordinate plan

kiruha [24]

Answer:

Perimeter of the dog park = 15.4 yards

Step-by-step explanation:

Coordinates of the vertices of the given triangle are,

P(1, 2), Q(1, 6), R(-4, 2)

Since distance between the two points $(x_1, y_1)$ and $(x_2,y_2)$ is,

d = $\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Length of PQ = $\sqrt{(1-1)^2+(2-6)^2}$

PQ = 4

Length of PR = $\sqrt{(1+4)^2+(2-2)^2}$

PR = 5

Length of QR = $\sqrt{(1+4)^2+(6-2)^2}$

QR = $\sqrt{25+16}$

= $\sqrt{41}$

= 6.4 yards

Therefore, perimeter of the given triangle = PQ + QR + PR

= 4 + 6.4 + 5

= 15.4 yards
