L = 6W
Area A = LW = 600. So, 6W(W) = 600, W2 = 600/6 = 100, so W = 10. Then L = 600/10 = 60.
Perimeter P = 2L + 2W = 2(60) + 2(10) = 120 + 20 = 140.
Answer:
Prime numbers are numbers that only two factors, 1 and itself. Example: 2,3,5,7,11,13,17,19...............47 etc l. NB: 1 is not a prime number. All the multiples of the prime numbers are composite numbers

So start with your standard numbers. Divide 1.6 by 4 and you get 0.4
With the exponents, since you’re dividing, you keep the base and subtract the exponents. So 3-6=-3
You’d get 0.4 x 10 to the -3 but that’s not correct scientific notation because you have to have a value 1 or larger.
Move the decimal to the right one place (making the standard number larger) and make the exponent smaller to balance it out.
4 x 10 to the -4 power.
Let's represent the smaller number by x and the larger number x+23
x+x+23=65 x+23=21+23=44 So the two numbers are 21 and 44
2x+23=65
2x+23-23=65-23
2x=42
2x/2=42/2
x=21
