Suppose a rectangular garden plot has a length that can be expressed as x+2 feet and a width expressed as x+7 feet. Write a poly
mafiozo [28]

Answer:

Area = x^2 + 9x + 14

Perimeter = 4x + 18

Step-by-step explanation:

Given:

Length of rectangular garden = (x + 2) ft

Width = (x + 7) ft

Required:

a. Polynomial expression of the area of the garden

b. Polynomial expression of the perimeter of the garden

SOLUTION:

Area of the rectangular garden = length × width

Area = (x + 2)(x + 7)

Expand using the distributive property of multiplication

Area = x(x + 7) +2(x + 7)

Area = x^2 + 7x + 2x + 14

Area = x^2 + 9x + 14

Perimeter = 2(length) + 2(width)

Perimeter = 2(x + 2) + 2(x + 7)

Perimeter = 2x + 4 + 2x + 14

Collect like terms

Perimeter = 2x + 2x + 4 + 14

Perimeter = 4x + 18

pochemuha

Answer:

(3, 6) or x = 3 and y = 6

Step-by-step explanation:

у = 2x, x + y = 9 (using substitution)

x + 2x = 9

3x = 9

x = 3

y = 2x

y = 2(3)

y = 6
