Answer:
He should buy the 4 x 10 rug because it has the larger area.
Step-by-step explanation:
To find the area of a rectangle or square, you multiply length by width (A=l x w). 5x7=35 and 4x10=40, so 4 x 10 has the bigger area.
It would be the second one.
4(2x^2 + 5y^2)(2x^2 - 5y^2)

Answer:
The length of the first piece is 4 inches, that of the second is 8 inches and the third 19 inches.
Step-by-step explanation:
Total length of the steel = 31 inches
Let the length of the first piece = x
let the length of the second piece = y
Let the length of the third piece = z
So,
y = 2x
z = 4x + 3
x + 2x + 4x +3 = total length of the steel = 31
7x + 3 + 31
7x = 31 - 3
7x = 28
x= 4 inches
Thus; y = 2x = 2 × 4 = 8 inches
z = 4x +3 = 4×4 +3 =19 inches
∴The length of the first piece is 4 inches, that of the second is 8 inches and the third 19 inches.
