Answer:
Rational numbers
Step-by-step explanation:
A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. The number 8 is a rational number because it can be written as the fraction 8/1.
40=P x 10 x 5 / 100, use the solve function on the CAS calculator to find P
Answer:1125
Step-by-step explanation:
w=width
w+20=length
P=2l+2w
140=2(w+20)+2w
140=2w+40+2w
140=4w+40
140-40=4w
100=4w
w=100/4
w=25 m
l=25+20=45 m
A=lw
A=45*25
A=1125 sq m
