What is the perimeter of a rectangle where the area is 35 sq inches, (the length is 7inches and the width is 5 inches)?

The perimeter is 24 sq inches.

Step-by-step explanation:

In order to find perimeter, you must add together all the sides. So the equation would be (LxW)2 , or just Length plus Length plus Width plus Width. Therefore, it is either (7x5)2 or 7 + 7 + 5 + 5 which both equal 24 sq inches. Hope this helps!

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
