Answer:
Domain is R ( all real numbers)
Range is R (all real numbers)
5/4
Step-by-step explanation:
2(8x-3)-4(3x-5)=19
16x-6-12x+20=19
16x-12x-6+20=19
4x+14=19
4x=19-14
4x=5
x=5/4
1000 cm²
perimeter = 2 * length + 2 * width
2 * 5x + 2 * 2x = 140
10x + 4x = 140
14x = 140
x = 10
Length: 5x = 5(10) = 50
Width: 2x = 2(10) = 20
area = length * width
area = 50 cm * 20 cm
area = 1000 cm²
