Answer: 31 is the only prime number here since its factors are 1 and itself
Step-by-step explanation: since 70 has the factors, 10, 7, 5, 2, etc, it cannot be classified as a prime number.
85 and 49 have more factors than 1 and itself so it cannot be classified as a prime number either

Answer:
Step-by-step explanation:
After distributing:
Simplify further by combining like terms
One width and one length is half the perimeter.
90/2 = 45
Let the width = X
the length is 2 times the width so 2X
The sum of the two equals 45"
2X + X = 45
Simplify:
3x = 45
Divide both sides by 3:
x = 15
The width is 15 inches
Length = 30 inches.
Area = Length x width = 15 x 30 = 450 in^2
The area 450 in^2
