Step-by-step explanation:
garden a:
perimeter=2xlength+2xwidth = 2x(5x(2x-3))+2x(2x-3) = 20x-30 + 4x-6 = 24x-36 / 12(2x-3) feet
garden b:
perimeter= 5x+5 + 4x+2 + 8x-8 = 17x - 1 feet
Answer:
<u>garden A </u>
Width (W) = 2x - 3
Length (L) = 5(W)
= 5 (2x - 3)
= 10x - 15
Perimeter A = 2L + 2W (perimeter of a rectangular garden)
= 2(10x - 15) + 2(2x - 3)
= 20x - 30 + 4x - 6
= 24x - 36
<u>garden B </u>
side 1 = 5x + 5
side 2 = 4x + 2
side 3 = 8x - 8
Perimeter B = sides (1 + 2 + 3)
= 5x+5 + 4x+2 + 8x-8
= 5x + 4x + 8x + 5 + 2 - 8
= 17x - 1
(-31,15)
Rotating 90 degrees clockwise is very simple:
(a,b) 90 degrees= (-b,a)
Very simple.
Just switch sides and add negative to the first term.
