Answer:

(-1,-2)

Step-by-step explanation:

There is a solution where the two expressions intersect. We can plug in what we know in the first equation in the second.

x= -1

y=3x+1

y= 3(-1)+1

y= -3+1

y= -2

Plugging y value in the equation to find x:

-2=3x+1

-3=3x

x= -1

Therefore, the point is (-1,-2)

<em>I hope this helps! :)</em>

19. Perimeter of rectangle = 2(l + b)

l = 25m

b = 16m

Perimeter of rectangular park = 2 (25 + 16)

= 50 + 32

= 82m

Perimeter of square park = 82m

(given that, perimeter of rectangular and square park are equal)

Perimeter of square = 4a

4a = 82

a = 82/4

a = 20.5m

Area of square park = a²

= 20.5²

= 420.25m²

20. Perimeter of regular hexagon = 6a

a = 2.5

6a = 6 × 2.5

= 15cm

21. Perimeter of regular decagon = 10a

a = 8

10a = 10 × 8

= 80cm
